23.The U. S. Department of Health, Education, and Welfare collected sample data for 1525 women, aged 18 to 24. That sample group has a mean serum cholesterol level of 191.7 mg/100mL with a standard deviation of 41.0 mg/100mL. Suppose we want to test the hypothesis that the mean serum cholesterol level of all women in the 18-24 age bracket is 200 mg/100mL. Given the 90% confidence interval of the mean serum cholesterol level of all women in the 18-24 age bracket is (190.0, 193.4), which of the following statements is true?
a.Because 0 is not contained within this confidence interval, we reject H0and conclude that there is sufficient evidence to warrant rejection of the claim that the mean serum cholesterol level of all women in the 18-24 age bracket is 200 mg/100mL.
b.Because 191.7 mg/100mL is contained within this confidence interval, we fail to reject H0and conclude that there is not sufficient evidence to warrant rejection of the claim that the mean body temperature of all healthy adults is 191.7 mg/100mL.
c.Because 200 mg/100mL is not contained within this confidence interval, we reject H0and conclude that there is sufficient evidence to warrant rejection of the claim that the mean serum cholesterol level of all women in the 18-24 age bracket is 200 mg/100mL.
d.We are 95% confident that the interval from 190.0 to 193.4 actually does contain the true value of the population mean serum cholesterol level.
e.There is a 90% chance that the true value of the population mean serum cholesterol level will fall between 190.0 and 193.4.
