Question 1183120: A statistics practitioner calculated the mean and the standard deviation from a sample of 51 observations. The sample mean= 120 and sample standard deviation= 15. To estimate the population mean with 90% confidence, the interval would have the lower and upper limits as:
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
half-interval for a 90% CI t-dist would be t (0.95, df=50)*s/sqrt(n)
=1.676*15/sqrt(51)=3.52
CI=(116.48, 123.52)
