Q.7 - The Practice of Statistics for AP

Question

A change is made that should improve student satisfaction with the parking situation at a local high school. Right now, 37% of students approve of the parking that’s provided. The null hypothesis $H_0:p>0.37$ is tested against the alternative$H_a:p=0.37$.

Step-by-Step Solution

Answer

The population value is $0.37$ as per null hypothesis and population value more than $0.37$ as per alternative hypothesis, the problem is incorrect according to the hypotheses.

Step 1: introduction

Given,

$37\%$ of students approve of the parking that’s provided and the hypotheses are tested against one another.

Step 2: explanation

calculating the hypotheses,

population value =$0.37$as per null hypothesis

$\Rightarrow H_0:p=0.37$

population value more than$0.37$as per alternative hypothesis

$\Rightarrow H_a:p>0.37$

The population value =$0.37$as per null hypothesis and population value more than $0.37$as per alternative hypothesis, the problem is incorrect according to the hypotheses.
