The Answer of A random sample of n = 144 measurements was selected from a population with unknown mean μ and standard deviation σ. Calculate a 90% confidence interval if $\bar { x } = 3.55 \text { and } s = .49$

A Random Sample of N = 144 Measurements Was Selected xˉ=3.55 and s=.49\bar { x } = 3.55 \text { and } s = .49xˉ=3.55 and s=.49

A Random Sample of N = 144 Measurements Was Selected $\bar { x } = 3.55 \text { and } s = .49$
