A researcher wants to know how long it takes, on average, for a certain species of bacteria to divide. She watches 23 cells through a microscope and times how long it takes them to divide. She obtains the following data, in hours: .2, 8.8, 6.5, 9.8, 8.1, 9.2, 9.1, 8.4, 7.3, 8, 7.9, 7.4, 8.4, .7, 6.9 .2, 7. ,8.4, 8.6, 8 .5 8. ,9.8, 92,8 '40) Nw Assuming the population standard deviation is 0' = 1.2, construct a 98% confidence interval for the average time it takes this species of bacteria to divide. j: M N salt: Margin of Error: E = We are 98% confident that this species of bacteria takes, on average, between divide. hours to
