A random sample of 64 observations produced the following summary
statistics: x = .36 and s2 = .034.
a. Test the null hypothesis that µ = .397 against the alternative hypothesis that µ<0.397, using="" α="">
b.Test the null hypothesis that µ = .397 against the alternative hypothesis that µ ≠0.397, using α = .10.
Interpret the result.(Using Table II and Formula:image2)
