Making the statement is itself a type II error. c. Whether the null hypothesis is true or not makes no difference in terms of type II error. d. Whether or not the researcher rejects the null hypothesis makes no difference in terms of type II error. e. Accepting the null hypothesis when it actually is true means that the researcher concludes that there is no difference between 10 mcg and 20 mcg of vitamin D3 in preventing osteoporosis, and there is no error. f. Accepting the null hypothesis when it actually is false means that the researcher concludes that there is no difference between 10 mcg and 20 mcg of vitamin D3 in preventing osteoporosis, when there actually IS a difference.
