Who can help me solve these two statistics problems Thanks in advance for your help!?

(1) Suppose N = 60,000, n =15,000, and s =50

.(a) compute the standard error of mean (x) using the finite population correction factor

(b) Repeat part a assuming n =30,000

(c)Repeat part a assuming n = 60,000

(d)Compare parts (a), (b), and (c), and describe what happens to the standard error of the mean (x) as n is increased .

(2) In order to evaluate the reasonableness of a firm’s stated value of its parts inventory, an auditor randomly samples 50 of the total of 400 parts in stock, prices each part, and reports the results shown in the table below. Use this information to answer the following questions
