Question

A local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 30 minutes. What type of tail is this test using?

Answer 1

Right tailed test

Explanation:

The null hypothesis is:

`H_o: \mu \le 30`

The alternative hypothesis is:

`H_a: \mu > 30`

This is a right-tailed test since the alternative hypothesis is greater than 30

Suppose the level of significance is 0.05 and we are given a p-value less than 0.05.

Then, we reject the null hypothesis.
