Ask Custom Question

A restaurant claims that its speed of service time is less than 18 minutes. A random selection of 36 service times was collected, and their mean was calculated to be 17.1 minutes. Their standard deviation is 3.1 minutes. Is there enough evidence to support the claim at alpha = .08. Perform an appropriate hypothesis test, showing each important step. (Note: 1st Step: Write Ho and Ha; 2nd Step: Determine Rejection Region)

Solution Summary

A hypothesis test is conducting to confirm the service time at a restaurant.

Solution Preview

First write the hypothesis. What we want to establish is taken as alternate hypothesis and the status quo is taken as null hypothesis. Therefore, we have
Ho: mu=>18 minutes
H1: mu<18 minutes

This is one ...
