A lab assistant has been doing lab work of pipetting into a 96 well plate. They have been pipetting over a period of several months, during which time their pipetting ability has remained constantly good. Usually, the assistant pipettes 4-96 well plates 5 times a day. The standard deviation of their times is 3.56 minutes. During the month the lab assistant recorded their times to pipette 4-96 well plates. The assistant has chosen a random sample of 61 of these times. For these 61 times, the mean was 25.70 minutes. Find a 0.95 confidence interval for the mean. a. Compute for E
