The recommended daily Calcium intake for women between the ages of 21 and 50 is 1000 mg per day. The health services at a college are concerned that women at the college get less Calcium than that, so they take a random sample of female students in order to test the hypotheses Ho: u = 1000, Ha: u < 1000. Prior to the study, they estimate that the power of their test to reject u = 1000 when u = 900 is 0.85. Which of the following is the best interpretation of this value? O The probability of failing to reject the null hypothesis when the parameter value is 1000. O The probability of making a Type II error. O The probability of failing to reject the null hypothesis when the parameter value is 900. The probability of rejecting the null hypothesis when the parameter value is 900. O The probability of rejecting the null hypothesis when the parameter value is 1000.
