A random sample of n = 9 values taken from a normally distributed population with a population vadance of 3G resulted in The sample values shown below. Use the sample valua to construct a 90% conﬁdence interval estimate lor the population mean 52 46 54 45 45 52 46 61 49 Q1 The 90% cnnﬁdence interval is ,
(Round to two decimal places as needed Use ascending order)

Here is the solution... View the full answer

Mean=50.11       Standard deviation s=5.23 Sample size =    9 Critical... View the full answer

x̄= 50.11 variance=36 sigma= sqrt(variance)=6 n= 9 althought here sample size is small but we can use... View the full answer
