A researcher wants to know how long it takes, on average, for a certain species of bacteria to divide. She watches 16 cells through a microscope and times how long it takes them to divide. She obtains the following data, In hours: 5.8, 6.6, 5.5, 5.8, 5.1, 7.4, 9.2, 8.3, 10.9, 7.5, 3.1, 3, 4.9, 7.8, 6.5, 6.8 Assuming the population standard deviation is o = 2, construct a 96% confidence interval for the average time it takes this species of bacteria to divide. T = N R Margin of Error: E = We are 96% confident that this species of bacteria takes, on average, between hours and hours to divide
