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: 10, 8.6, 10.1, 8.4, 6.4, 11.8, 7.2, 8.5, 6.3, 5.8, 7.4, 7, 9.5, 9.8, 7.6, 7.8, 9.6, 10.3, 10.3, 5.6, 11.1, 4.9 Assuming the population standard deviation is o = 1.8, construct a 97% confidence interval for the average time it takes this species of bacteria to divide. X = 8|2 N 82 = = Margin of Error: E = We are 97% confident that this species of bacteria takes, on average, between hours and hours to divide.
