The mean of the times (in minutes) it takes a lab technician to perform a certain task is of interest. The lab technician was observed on 5 different occasions and 14.5, 14.2, 14.4, 14.3 and 14,6 were recorded. a) Assume that data are random sample from a normal distribution with variance 0.02. b)Can we conclude that true mean time to perform this task is different than 14 minutes? Let α = 0.05. Calculate P-Value of the test.
