Chapter 9: Q. 9.4 (page 508)

On a state driver's test, about 40%pass the test on the first try. We want to test if more than 40%pass on the first try. Fill in the correct symbol (=,鈮�,鈮�,<,鈮�,>)for the null and alternative hypotheses.

a.H0:p-0.40

b.Ha:p-0.40

Short Answer

Expert verified

a. Null hypotheses is less than or equal to0.40.

b. Alternative hypotheses is greater than0.40.

Step by step solution

01

Introduction

According to the null hypothesis, there is no difference between a proportion and the population's proportion.

The opposition of null hypotheses is stated by the alternative hypothesis

02

Explanation  (part a)  

On the first try not more than 40%is known as null hypotheses.

It is denoted by H0.

So,

H0:p鈮�0.40

03

Explanation (part b)

On the first try more than 40%is known as alternative hypotheses.

It is denoted by Ha.

So,

Ha:p>0.40
