Q.8 - The Practice of Statistics for AP

Question

A change is made that should improve student satisfaction with the parking situation at your school. Right now, 37% of students approve of the parking that’s provided. The null hypothesis $H_0:\widehat{p}=0.37$ is tested against the alternative $H_d:\widehat{p}\ne 0.37$.

Step-by-Step Solution

Answer

The population value = $0.37$ as per null hypothesis and is not equal to$0.37$ as per alternative hypothesis, the problem is incorrect.

Step 1: introduction

Given,

A change is made that should improve student satisfaction with the parking situation at your school 

The students approve of the parking that’s provided is $37\%$

Step 2: explanation

Calculating the hypotheses,

The population value is $0.37$ as per the null hypothesis

$\Rightarrow H_0:p=0.37$

The population value is not equal to $0.37$ as per alternative hypothesis

$\Rightarrow H_a:p\ne 0.37$

The population value = $0.37$ as per null hypothesis and is not equal to $0.37$ as per alternative hypothesis, the problem is incorrect.
