When a population is finite, the formula that determines the standard errorof the mean needs to be adjusted. If N is the size of the population and nis the size of the sample (where n ≥ 0.05N), the standard error of the meanis shown below. The finite population correction factor is given by theexpression (N-n)/(N-1). Determine the finite population correctionfactor for each of the following.(a) N = 1700 and n = 850(c) N = 1700 and n = 125(e) What happens to the finite population correction factor as the samplesize n decreases but the population size N remains the same?(b) N = 1700 and n = 170(d) N = 1700 and n = 85(a) The finite population correction factor is(Round to three decimal places as needed.)
