Question

The distribution of diastolic blood pressures for the population of female diabetics between the ages of 30 and 34 has an unknown mean ? and a standard deviation of ? = 9 mmHg. It may be useful to physicians to know whether the mean ? of this population is equal to the mean diastolic blood pressure of the general population of females of this age group, which is 74.5 mmHg. a. What is the null hypothesis of the appropriate test b. What is the alternative hypothesis? c. A sample of ten diabetic women is selected; their mean diastolic blood pressure is x? = 84 mm HG. Using this information, conduct a two sided test at the ?=0.05 level of significance. What is the p –value of the test? d. What conclusion do you draw from the results of the test? e. Would your conclusion have been different if you had chosen ?=0.01 instead of ?=0.05
