c) The test statistic is: z = 9.71.
d) The correct option is of: A. Yes.
e) The confidence interval is of: 0.0819 < p < 0.1336.
What are the hypothesis tested?
At the null hypothesis, it is tested if there is not enough evidence that the proportion for men is greater, that is, the subtraction is not greater than 0:
[tex]H_0: p \leq 0[/tex]
At the alternative hypothesis, it is tested if there is evidence that the proportion for men is greater, that is, if the subtraction is greater than 0, hence:
[tex]H_1: p > 0[/tex]
We have a right-tailed test, as we are testing if the mean is greater than a value, with a significance level of 0.01, hence the critical value is of:
z = 2.327.
Thus the decision rule regarding the test statistic is given as follows:
z < 2.327 -> not enough evidence of difference -> do not reject the null hypothesis.z > 2.327 -> enough evidence of difference -> reject the null hypothesis.What are the mean and the standard error of the distribution of differences?For each sample, the mean and the standard error are given as follows:
Men: [tex]p_m = \frac{88}{800} = 0.11, s_m = \sqrt{\frac{0.11(0.89)}{800}} = 0.0111[/tex]Women: [tex]p_w = \frac{6}{2750} = 0.0022, s_w = \sqrt{\frac{0.0022(0.9978)}{2750}} = 0.0009[/tex]Hence, for the distribution of differences, the mean and the standard error are given as follows:
Mean: p = 0.11 - 0.0022 = 0.1078.Standard error: s = sqrt(0.0111² + 0.0009²) = 0.0111.What are the test statistic and the conclusion:The test statistic is given by the division of the mean by the standard error of the sampling distribution of the difference of sample proportions, hence:
z = 0.1078/0.0111 = 9.71.
z > 2.327 -> enough evidence that the proportion is greater.
What is the confidence interval?The confidence interval is obtained as the mean plus/minus the multiplication of the standard error and of the critical value.
Then the bounds of the interval are:
Lower bound: 0.1078 - 2.327 x 0.0111 = 0.0819.Upper bound: 0.1078 + 2.327 x 0.0111 = 0.1336.More can be learned about the test of an hypothesis at https://brainly.com/question/13873630

Use the Pythagorean theorem to find the side of the right triangle. Length 3m, With 2m+14, 5m
Answers
The side lengths of the triangle are 11.1, 21.4, and 18.5 units.
What is the Pythagorean theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
The given sides of the right triangle are 3m, 2m+14, and 5m.
As per the Pythagorean theorem, it follows:
(2m + 14)² = (3m)² + (5m)²
4m² + 196 + 56m = 9m² + 25m²
30m² -56m - 196 = 0
15m² - 28m - 98 = 0
[tex]m=\frac{-(-28)\pm\sqrt{(-28)^2-4(15)(-98)}}{2(15)}\\\\m=\frac{28\pm\sqrt{6664}}{2(15)}\\\\m =\frac{28\pm81.6}{2(15)}\\\\m=3.7\text{ or } m=-1.8[/tex]
Since the lengths cannot be negative, the value of m is m = 3.7.
Therefore, the side lengths of the triangle are:
3m = 3(3.7)
= 11.1
2m + 14
= 2(3.7) + 14
= 21.4
and,
5m
=5(3.7)
= 18.5
Hence, the side lengths of the triangle are 11.1, 21.4, and 18.5 units.

has one repeated real root
q = ______
Answers
Answer:
q = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
then the nature of the roots can be found using the discriminant
Δ = b² - 4ac
• if b² - 4ac > 0 then roots are real and irrational
• if b² - 4ac = 0 then the roots are real and equal
• if b² - 4ac < 0 then the roots are not real
qx² - 6x + 18 = 0 ← is in standard form
with a = q , b = - 5 , c = 18
for one repeated (equal) real root , then
b² - 4ac = 0 ( substitute values )
(- 6)² - (4 × q × 18) = 0
36 - 72q = 0 ( subtract 36 from both sides )
- 72q = - 36 ( divide both sides by - 72 )

Answers
Using the Green's Theorem, the one along which the work done by the force is 11π/16.
In the given question we have to find the one along which the work done by the force is the greatest.
The given closed curves in the plane is
[tex]F(x,y)=\left(\frac{x^{2}y}{4} + \frac{y^3}{3}\right)\hat{i}+x\hat{j}[/tex]
Suppose C be a simple smooth closed curve in the plane. It is also oriented counterclockwise.
Let S be the interior of C.
Let P = [tex]\frac{x^{2}y}{4} + \frac{y^3}{3}[/tex] and Q = x
So the partial differentiation is
[tex]\frac{\partial P}{\partial y}=\frac{x^2}{4}+y^2[/tex] and [tex]\frac{\partial Q}{\partial x}[/tex] = 1
By the Green's Theorem, work done by F is given as
W= [tex]\oint \vec{F}d\vec{r}[/tex]
W= [tex]\iint_{S}\left ( \frac{\partial Q}{\partial x}-\frac{\partial P}{\partial y} \right )dxdy[/tex]
W= [tex]\iint_{S}\left ( 1-\frac{x^2}{y}-y^2 \right )dxdy[/tex]
Let C = x^2+y^2 = 1 and
x = rcosθ, y = rsinθ
0≤r≤1; 0≤θ≤2π
There;
W = [tex]\int_{r=0}^{1}\int_{\theta=0}^{2\pi}\left ( 1-\frac{r^2\cos^2\theta}{4}-r^2\sin^2\theta \right )\left|\frac{\partial(x,y)}{\partial{r,\theta}}\right|d\theta dr[/tex]
and [tex]\frac{\partial (x,y)}{\partial(r, \theta)}=\left|\begin{matrix}\cos\theta &-r\sin\theta \\ \sin\theta & r\cos\theta\end{matrix} \right |[/tex] = r
Thus;
W = [tex]\int_{r=0}^{1}\int_{\theta=0}^{2\pi}\left ( 1-\frac{r^2\cos^2\theta}{4}-r^2\sin^2\theta \right )rd\theta dr[/tex]

The number of days in July = 31
The number of days in August = 31
The maturity date for a loan taken out on June 6 for 73 days is August 28.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The date on which the loan was taken = June 6.
The number of days for the loan to mature = 73 days.
Now,
The number of days in June is 30
The number of days in July = 31
The number of days in August = 31
Now,
There are (30 - 6) = 24 days remaining in the month of June.
So,
24 + 31(July) = 45 days.
Now,
73 - 45 = 28 days need to be taken from August.
So,
45(July) + 28(August) = 73 days.
This means,
The maturity date is August 28.
Thus,
The maturity date for a loan taken out on June 6 for 73 days is August 28.

Rows for Berkeley students have a 80% chance of being placed in the train set and 20% chance of placed in the test set.Given that a row is in the test set, what is the probability that it corresponds to a Stanford student? Assign that probability to prob_furd. Hint: Remember that there are 77 Berkeley students and 23 Stanford students in coordinates Hint 2: Thomas' last name is Bayes (15 points)
Answers
The probability that a row in the test set belongs to a Stanford student is 0.4167.
Given that,
Thomas has come up with a plan for dividing the training and test set. From the coordinates, for each row:
Students from Stanford have a 50% chance of being assigned to the test set and a 50% chance of being assigned to the train set for their rows.
20% of Berkeley students' rows are assigned to the test set, while 80% are assigned to the train set.
We have to find what is the probability that a row in the test set belongs to a Stanford student.
We know that,
Let us define events are as
B: Student in the coordinate is Berkeley student
S: Student in the coordinate is Stanford student
Tr: Rows is in the train set
Ts: Rows is in the test set
Since there are 77 Berkeley student and 23 Stanford student in coordinate
Hence,
P(B) = Probability that Student in the coordinate is Berkeley student
= 77/(77+23) = 77/100 = 0.77
P(S) = Probability that Student in the coordinate is Stanford student =23/(77+23) = 23/100 = 0.23
Conditional probability,
P(Ts|B) = Probability that Student placed in the test set when the student is Berkeley student = P(Ts|B) = 0.20
P(Ts|S) = Probability that Student placed in the test set when the student is Stanford student = P(Ts|S) = 0.5
Required probability,
Given that a row is in the test se, Probability that it corresponds to a Stanford student =
Probability of Stanford students = P(S|Ts) =
By Bayes theorem,
P(S|Ts) = P(Ts|S)×P(S)/P(Ts|S)×P(S)+P(Ts|B)×P(B)
P(S|Ts) = 0.22×0.5/0.22×0.5+0.20×0.77
P(S|Ts) = 0.4167
Therefore, The probability that a row in the test set belongs to a Stanford student is 0.4167.

Answers
The minimum grade require to get grade of B is 78.6.
In the given that;
μ = 65 (average grade)
σ = 20 (standard deviation)
X ≈ N(μ, σ^{2})
Let c be the minimum grade to required to get grade of B
Percentage of data below c = 10% + 15% + 50% =75%
If we convert the percentage to probability = 75%/100% = 0.75
Now to get the value of c we solve the equation
P(X < c) = 0.75
⇒P{(X-μ)/σ < (c-μ)/σ)=0.75
Here z = (X-μ)/σ follows normal (0,1)
z is the standard normal variable
⇒P(z<(c-μ)/σ)=0.75
⇒P(z< (c-65)/20)=0.75
From z table we get, (c-65)/20 = 0.68
⇒(c-65)/20 = 0.68
⇒c= 78.6
