A bottled water distributor wants to determine whether the mean amount of water contained inâ 1-gallon bottles purchased from a nationally known water bottling company is actually 1 gallon. You know from the water bottling company specifications that the standard deviation of the amount of water is 0.008 gallon. You select a random sample of 50 bottles, and the mean amount of water perâ 1-gallon bottle is 0.995 gallon.
Required:
a. Is there evidence that the mean amount is different from 1.0 gallon?
b. What is the test statistic?
c. Compute theâ p-value and interpret its meaning.
d. Construct a 95% confidence interval estimate of the population mean amount of water perâ 1-gallon bottle.
Answers
Answer:
1. There is evidence that mean is different from 1.0 gallon
2. test statistic = -4.42
3. p value = 0.00001
4. 0.9928,0.9972
Step-by-step explanation:
h0: u = 1.0
h1: u not equal to 1.0
alpha = 0.05
sd = 0.008
n = 50
mean = 0.995
standard error se = 0.008/√50 = 0.00113
test statistics calculation
0.995-1/0.00113
= -0.005/0.00113
= -4.42
p value calculation
using the z test statistics and alpha = 0.05
the p value using a p value calculator = 0.00001
0.00001<0.05
so we Reject the null hypothesis
we conclude there is enough evidence that mean is different from 1.0
95% confidence interval
Z alpha/2 = 0.025
we find z value using excel function
NORMSINV (0.025)
|Z| = 1.96
Standard error se = 0.00113
margin of error E = 1.96 x 0.00113 = 0.0022148
confidence interval =
0.995 - 0.0022148, 0.995 + 0.0022148
= 0.9928, 0.9972

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
64x = 8
Solve for x.
64x = 8
Divide both sides with 64.
x = 8/64
x = 1/8
Thus,
The value of x is 1/8.

When solving -1/8 (x + 35) = - 7, what is the correct sequence of the operations?
1. multiply each side by -1/8, add 35 to each side
2. multiply each side by -1/8, subtract 35 from each side
3. multiply each side by -8, subtract 35 from each side
4. multiply each side by -8, add 35 to each side
Answers
Answer:
The correct option is 3.
Step-by-step explanation:
By multiplying each side by -8, you can get rid of the fraction. Then by subtracting 35 from both sides, you get what is x.

Step-by-step explanation:
Rearrange Terms

(-3i+4)(2i+1)
Distribute
-3(2i+1)+4(2i+1)
-6i^2-3i+4(2i+1)

-6i^2-3i+8i+4
Combine Liker Terms
-6i^2+5i+4
Solution
-6i^2+5i+4
Answer:
-2 + 5i
Step-by-step explanation:
Remember these rules:
real times real = real (e. g., 4(1) = 4)
real times imaginary: imaginary (e. g., 4(2i) = 8i)
imaginary times real imaginary
imaginary times imaginary: real with a negative sign (e. g., (-3i)(2i) = +6
Once again: work out (-3i)(2i). We get (i^2)(-6) = +6
In summary: your (4-3i)(1+2i) becomes 4 + 8i - 3i - (i^2)(-6), or
4 + 5i - 6, or -2 + 5i

La desviación estándar se puede calcular mediante la fórmula
S = √∑fx² / n - (∑fx / n) ²
La desviación estándar es 6,12
Poner los valores de la tabla en la hoja de Excel dada.
s = √381430 / 60 - (4770/60) ²
s = √6357.167 -6320.25
s = √36,917
s = 6,0759
Cuando se redondea daría 6,1
The standard deviation can be calculated using the formula
S= √∑fx²/n - (∑fx/n)²
The standard deviation is 6.12
Putting the values from the table in the given excel sheet.
s= √381430/60 - (4770/60)²
