Question:

2.5. Consider the Minitab output shown below.

One-Sample Z Test of µ = 30 vs not = 30 The assumed standard deviation = 1.2 N Mean SE Mean 95% CI Z P 16 31.2000 0.3000 (30.6120, 31.7880) * *

(a) Fill in the missing values in the output. What conclusion would you draw?

(b) Is this a one-sided or two-sided test?

(c) Use the output and the normal table to find a 99 percent CI on the mean.

(d) What is the P-value if the alternative hypothesis is H₁: µ > 30?
