Question

A local eat in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. th owner of the store has determined that home delivery will be successful only if the average time spent on delivery does not exceed 40 minutes. The owner has randomly selected 17 customers and delivered pizza to their homes in order to test whether the mean delivery time actually exceeds 40 minutes. Suppose the p value for the test was found to be .0293. state the correct conclusion.

Answer 1

Here, the null hypothesis is that the home deliveries exceeds 40 minutes. When the owner tested with 17 customers, the p-value for the test was found to be 0.0293, which was really low. The p-value can be from 0-1.

The p-value has to be higher than 0.05 in order for hypothesis to be considered reasonable. If the p-value is lower than 0.05, then the null hypothesis is not true.

Therefore, since the p-value is 0.0293 for deliveries exceeding 40 minutes is very low. This means that most of the deliveries are being made within the 40 minute time frame.
