A researcher develops a study to examine the effects of Keep Yourself Safe Screening (KYSS) on the incidence of intimate partner violence (IPV). The study level of significance is 0.05 The null hypothesis, that KYSS will have no effect on IPV, is found to be true. When reviewing the study for Type II errors, the reviewer understands that:
a. a level of significance of 0.01 would decrease the risk of a Type II error.
b. the level of significance does not affect the chance of a Type II error.
c. there is a 5% chance that the null hypothesis is false.
d. there is a 5% chance that the null hypothesis is true.

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.two years ago, when picking flowers in the mountains back of yosemite valley; i found a book. it was blotted and storm-beaten, all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however, many of the inner pages were well preserved. and although all were more or less stained and torn; whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today, its granite pages have been torn and blurred by the same storms that wasted the castaway book.
