The Answer of A sample of 8 measurements, randomly selected from a normally distributed population, resulted in the following summary statistics: $\bar { x } = 5.2 , s = 1.1 .$ . Test the null hypothesis that the mean of the population is 4 against the alternative hypothesis $\mu \neq 4 . \text { Use } \alpha = .05$

A Sample of 8 Measurements, Randomly Selected from a Normally xˉ=5.2,s=1.1.\bar { x } = 5.2 , s = 1.1 .xˉ=5.2,s=1.1.
