Application on the Norma Curve
The ampunt of time it takes for a pizza delivery is approximately normally distributed with a mean of 25 minutes and a standard deviation of 2 minutes. If you order a pizza, find the probability that the delivery time will be:
1. between 25-27 minutes
2. less than 30 minutes
3. less than 22.7 minutes

    7) A pizza chain advertises that they will deliver a pizza in no more than 20 minutes from when an order is placed. However, for a random sample of 7 orders, the mean delivery time was 22.7 minutes with a standard deviation of 4.3 minutes. At the 0.05 significance level, test the claim that the mean pizza delivery time exceeds 20 minutes.

    Pizza companies are competitive in the amount of time it takes to deliver the pizza. Is there a significant difference in the average time it takes to deliver a pizza between Pizza Hut and Dominos? The following data was collected from a sample of deliveries of both companies; test the hypothesis at a 0.01 level of significance with 10 degrees of freedom(assume unequal variances). Pizza Hut: sample mean = 18.68, sample standard deviation = 1.64, sample size = 5 Dominos:...
