A mechanic wants to show that more than 44% of car owners do not follow a normal maintenance schedule.
Identify the null hypothesis, H0, and the alternative hypothesis, Ha, in terms of the parameter p.

We need to conduct a hypothesis in order to test the claim that the true propotion is higher than 0.44, the system of hypothesis are .:  

Null hypothesis:  

Alternative hypothesis:  

When we conduct a proportion test we need to use the z statistic, and the is given by:  

(1)  

Step-by-step explanation:

Data given and notation

n represent the random sample taken

estimated proportion of interest (owners who do not follow a normal maintenance schedule)

is the value that we want to test

represent the significance level

z would represent the statistic (variable of interest)

represent the p value (variable of interest)
