     a) will be relatively large.                                                              b) will be relatively small.

     c) will equal one minus the level of significance.     d) will equal one minus the probability that the null hypothesis is

                                                                                               false.

42. If it's important to detect even a relatively small effect, increase the

     a) scope of the investigation.       b) sample size.     c) size of the effect.              d) retention region.

43. Reducing the size of the standard error produces a shrinkage in the

     a) retention region.                                                                         b) true sampling distribution.

     c) retention region or the true sampling distribution.                               d) retention region and the true sampling distribution.
