QUESTION &5.24: What is the required sample size?Hint: See L-11 pdf and lecture, page 11-12 5.24 To evaluate the success of a 1-year experimental program designed to increase themathematical achievement of underprivileged high school seniors, a random sample of participantsin the program will be selected and their mathematics scores will be compared with the previousyear's statewide average of 525 for underprivileged seniors. The researchers want to determinewhether the experimental program has increased the mean achievement level over the previousyear's statewide average. If a = .05, what sample size is needed to have a probability of Type IIerror of at most .025 if the actual mean is increased to 550? From previous results, o = 80.

Given information: α=0.05σ=80PType II≤0.025 Actual mean value is 550.

3. Dentists make many people nervous. To assess any effect of such nervousness on blood pressure, the systolic blood pressure of 60 subjects was measured both in a dental setting and in a medical setting (The Effect of the Dental Setting on Blood Pressure Measurement," Amer. J. of Public Health, 1983:1210- 1214). For each subject, the difference between dental setting pressure and medical setting pressure was computed; the resulting sample mean difference and sample standard deviation of the differences were 4.47 and 8.77 mmHg, respectively. o (a) Estimate the true mean difference between blood pressures for these two settings using a 99% confidence level. o (b) Does it appear that the true mean pressure is different in a dental setting than in a medical setting? Explain your reasoning.
