Question: 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

Output from a software package follows:

One-Sample Z: Test of mu = 20 vs > 20 The assumed standard deviation = 0.75 Mean StDev SE Mean Variable N 10 19.889 0.23

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

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

(c) Use the normal table and the preceding data to construct a 95% two-sided CI on the mean.

(d) What would the P-value be if the alternative hypothesis is H1: μ‰ 20?

One-Sample Z: Test of mu = 20 vs > 20 The assumed standard deviation = 0.75 Mean StDev SE Mean Variable N 10 19.889 0.237 ? ?
