Output from a software package follows:

(a) Fill in the missing items. What conclusions would you draw?

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

(c) If the hypothesis had been H₀: μ= 98 versus H₀: μ > 98, would you reject the null hypothesis at the 0.05 level of significance? Can you answer this without referring to the normal table?

(d) Use the normal table and the preceding data to construct a 95% lower bound on the mean.

(e) What would the P-value be if the alternative hypothesis is H₁ : μ ‰  99?
