1. In a study of the length of time that students require to earn bachelor's degrees, 80 students are randomly selected and they are found to have a mean of 4.8 years. Assuming that the population standard deviation is known to be 2.2 years. Construct a 95% confidence interval of the population mean. How do you know this is a ZInterval problem? Does the resulting confidence interval contradict the fact that 39% of students earn their bachelor's degrees in 4 years?
