A study done by researchers at a university concluded that ​70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and​ 95% confidence interval for the​ study?

Answer:

Step-by-step explanation:

Given that:

The sample proportion [tex]\hat p = 0.70[/tex]

The sample size n = 1800

At 95% confidence interval level:

The level of significance = 1 - 0.95 = 0.05

Critical value: [tex]Z_{0.05/2} = Z_{0.025} = 1.96[/tex]

Thus, the Margin of Error E = [tex]Z_{\alpha/2} \times \sqrt{\dfrac{\hat p ( 1- \hat p)}{n}}[/tex]

[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 1-0.70)}{1800}}[/tex]

[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 0.30)}{1800}}[/tex]

[tex]= 1.96 \times \sqrt{\dfrac{0.21}{1800}}[/tex]

[tex]= 1.96 \times \sqrt{1.16666667\times 10^{-4}}[/tex]

the Margin of Error E = 0.021

At 95% C.I for the population proportion will be:

[tex]= \hat p \pm Z_{\alpha/2} \sqrt{\dfrac{\hat p(1- \hat p)}{n}}[/tex]

= 0.70 ± 0.021

= (0.70 - 0.021, 0.70 + 0.021)

= 0.679, 0.721)

Answer: 12

Step-by-step explanation:

Since value of y varies directly with x, we introduce a constant, k which will give:

y = kx

If x = 4, then y = 20 we then calculate the value of k.

y = kx

20 = 4k

k = 20/4

k = 5

We then find the value of x when y = 60. This will be:

y = kx

60 = 5x

x = 60/5

x = 12

The value of x is 12 when y is 60

Answer:

10:51

Step-by-step explanation:

Given that :

Distance from A to B = 130km

Departure time = 8 : 15

Average speed = 50 km/hr

Recall :

Speed = distance / time

Time = distance / speed

Time = (130 km) ÷ (50km/hr)

Time = 130 / 50

Time = 2.6 hours = 2 hours + (0.6 * 60) = 2 hours 36 minutes

Arrival time = (8:15) + (2 hours 36 minutes) = 10:51

Answer:

your answer is 560 am I correct.

8×70=560 /560 =8

70

7×80=560. / 560 =7

80

Step-by-step explanation:

Answer:

The volume of the geometric solid produced is 391 cubic cm ⇒ A

Step-by-step explanation:

When a right triangle is rotated about its vertical leg 360°, then it formed a cone its radius is the horizontal leg of the triangle and its height is the vertical lege of the triangle.

The rule of the volume of the cone is V = [tex]\frac{1}{3}[/tex] π r² h, where

∵ Triangle XYZ is rotated 360° about the vertical side YZ

∴ It formed a cone with a radius = XZ and a height = YZ

∵ [tex]\frac{YZ}{XZ}=tan(60)[/tex]

∵ YX = 6√3

∴ [tex]\frac{6\sqrt{3}}{XZ}=tan(60)[/tex]

∵ tan(60) = √3

∴ [tex]\frac{6\sqrt{3}}{XZ}[/tex] = √3

→ By using cross multiplication

∴ 6√3 = XZ(√3)

→ Divide both sides by √3

∴ 6 = XZ

∵ XZ = r and YZ = h

∴ r = 6 and h = 6√3

→ By using the rule of the cone above

∵ V = [tex]\frac{1}{3}[/tex] (π) (6)² (6√3)

∴ V ≅ 391 cm³

∴ The volume of the geometric solid produced is 391 cubic cm

Answer:

The President can exercise his emergency powers in three types of emergencies: national emergency, state emergency, and financial emergency.

National Emergency is imposed by the President on request by the Prime Minister’s cabinet of ministers. Article 352 of the Indian Constitution states that an emergency can be called in the event of imminent danger to the national security due to armed rebellion, war or external aggression.

State Emergency is often referred to as President’s Rule. State emergency is declared under Article 356, in the event when the state government collapses and the constitutional machinery fails in a particular state. It can be imposed for a period of six months and can last only for three years with parliamentary consent required every six months. The Governor, the President’s representative in the state, governs the state under emergency in the name of the President.

Financial Emergency is imposed by the President if he reckons financial stability of the country is in danger. Article 360 empowers the President to declare this emergency on the condition that it would be approved by the Parliament within two months of its enforcement.

Answer:

10 units

Step-by-step explanation:

Formula to find the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

d = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Distance between two points (0, -7) and (-6, 1) will be,

d = [tex]\sqrt{(0+6)^2+(-7-1)^2}[/tex]

  = [tex]\sqrt{36+64}[/tex]

  = [tex]\sqrt{100}[/tex]

  = 10

Therefore, distance between the given points is 10 units.
