Question

A random sample of 40 students was selected from students who took the statistics course this semester. The average time for a sample of students in the library is 8.8 hours of time. Assuming normal population distribution time is normally with a standard deviation of 5.2 hours,

(i) obtain 90% interval results for the time the university student population is in the library in time.

(ii) determine the sample size required to estimate the time the university student population is in the library if the sampling error is almost 1.5 hours of time with an information level of 99%.
