A student from the department of Mathematical and Computational Sciences [MCS] is working on his project. He is interested in estimating a, the average study hours per week of M08 students. He divided the students into three strata: Mathematics, Computer Science, and Statistics. The summar;r data are given in the following table. Population Sample Sample Standard Size Mean Deviation Mathematics N1 = 1500 25 2 Computer Science N2 = 3000 [a] Find a point estimate for a. Show all the steps. Circle the final answer. [b] Find a point estimator for the total study hours per week for statistics students. Show all the steps. Circle the nal answer. [c] Find the overall sample size n to estimate u with a bound on the error of estimation equal to 2 hours using Neman allocation. Show all the steps. Circle the nal answer. [d] Use part (c) to nd the sample size allocated to Computer Science? Show all the steps. Circle the final
