#27). Both photos are the same equation.
Transcribed Image Text:A food delivery service claims that it delivers orders to customers in 32.4 minutes or less, on average.
However, many people report that their recent orders have taken much longer to arrive. A secret shopping
firm would like to test the company's claim. The firm collected data from 187 randomly selected orders
and found that the average delivery time was 32.79 minutes with a standard deviation of 3.84 minutes.
Using α Η
greater than 32.4 minutes. Use the critical value method.
0.05, test the hypothesis that the average delivery time from this food delivery service is
State the null and alternative hypothesis for this test.

Determine if this test is left-tailed, right-tailed, or two-tailed.
O two-tailed
O left-tailed
O right-tailed
Should the standard normal (z) distribution or Student's (t) distribution be used for this test?
O The standard normal (z) distribution should be used
O The Student's t distribution should be used
Determine the critical value(s) for this hypothesis test. Round the solution(s) to four decimal places. If
more than one critical value exists, enter the solutions using a comma-separated list.
Determine the test statistic. Round the solution to four decimal places.
Determine the appropriate conclusion for this hypothesis test.
O The sample data provide sufficient evidence to reject the null hypothesis that the average food
delivery time from this company is 32.4 minutes or less and thus we conclude that average food
delivery time is likely greater than 32.4 minutes.
