A researcher wants to know how long it takes, on average, for a certain species of bacteria to divide. She watches 25 cells through a microscope and times how long it takes them to divide. She obtains the following data, in hours: 5.9, 9.3, 6.3, 5.7, 3.3, 4.9, 7, 7.4, 3.8, 8.5, 10.4, 8.4, 12.4, 7.5, 3.3, 6.9, 9.8, 5.2, 7.7, 8.6, 9.9, 3.9, 5.8, 5.9, 5.2 Construct a 95% confidence interval for the average time it takes this species of bacteria to divide. D = N R Margine of Erron E = We are 95% confident that this species of bacteria takes, on average, between hours and hours to divide
