Perform an appropriate hypothesis test for the following. A pizza delivery chain claims that it will deliver your pizza in no more than 20 minutes from when the order is placed. Being a skeptic, you decide to test and see if the mean delivery time is actually more than 20 minutes. For the simple random sample of 7 customers who record the amount of time it takes of each of their pizzas to be delivered, the mean is 22.7 minutes with a standard deviation of 4.3 minutes. Test the pizza chain's claim at 0.05 level of significance. 1. H: H : 2. 0 = 3. Calculate the test statistic 4. Draw the picture and find the p - value 5. compare p and ox 6. make a decision 7. write your conclusion
