QUESTION 1 Suppose average pizza delivery times are normally distributed with an unknown population mean and a population standard minutes deviation of six minutes. A random sample of 28 pizza delivery restaurants is taken and has a sample mean delivery time of 36 Identify the following: a. X = b. J = C. n= O a. X = 36 b. O = 28 c. n = 6 O a. X = 36 b. 0 = 6 c. 17 = 28 O a. X = 28 b. 0 = 6 c. n = 36 O a. X = 6 b. O = 28 c. n = 36
