Help needed urgently A SRS of 25 commuters to the Washington DC areaare selected, and each is asked how far theycommute to work each day. In the sample, the meandistance is 39 miles and the sample standarddeviation is 6 miles. Assume that in the populationof all commuters to the D.C. area, daily commutingdistance follows a normal distribution, with somemean μ. A 90% confidence interval for thepopulation mean commuting distance based onthese data is39391.645 miles1.708 miles(37.03, 40.97)(36.95, 41.05)

Given data,n=25The sample mean x=39Sample sd s=6Construct 90% CI?
