A researcher wants to know how long it takes, on average, for a certain species of bacteria to divide. She watches 22 cells through a microscope and times how long it takes them to divide. She obtains the following data, in hours: 7.4, 8.6, 6.6, 7.3, 9.1, 8.3, 8.9, 7.3, 9, 8.9, 8.4, 9.3, 7.4, 8.8, 8, 7.2, 10, 7.9, 7.4, 7.3, 7, 8.6 Assuming the population standard deviation is o = 1, construct a 90% confidence interval for the average time it takes this species of bacteria to divide. za = Margin of Error: E = We are 90% confident that this species of bacteria takes, on average, between hours and hours to divide.
