Construct a 90% confidence interval for the mean starting salaries of the CFA charterholders if a sample of 100 recent CFA charterholders gives a mean of 50. Assume that the population variance is 900. All measurements are in $1,000.A. 50 ± 1.645(30).B. 50 ± 1.645(3).C. 50 ±...
,n} in the general case. Sometimes it may be preferable to construct a confidence interval for logλj. By the delta method, n(logλ^j−logλj)→DN(0,Wjj/λj2). If the population is normal, then the natural logarithm is a variance stabilizing transformation since Wjj/λj2=2, and...
