Question: Use the information given in the previous exercise to determine if there is sufficient evidence to conclude that the mean pulse rate in a dental

Use the information given in the previous exercise to determine if there is sufficient evidence to conclude that the mean pulse rate in a dental setting differs from the mean pulse rate in a medical setting. Use a significance level of 0.05.
In previous exercise
Dentists make many people nervous. To see whether such nervousness elevates blood pressure, the blood pressure and pulse rates of 60 subjects were measured in a dental setting and in a medical setting (€œThe Effect of the Dental Setting on Blood Pressure Measurement,€ American Journal of Public Health [1983]: 1210€“1214). For each subject, the difference (dental setting blood pressure minus medical setting blood pressure) was calculated. The (dental€“medical) differences were also calculated for pulse rates. Summary statistics follow.

Do these data strongly suggest that mean blood pressure is higher in a dental setting than in a medical setting? Test the relevant hypotheses using a significance level of 0.01.

Mean Difference 4.47 Standard Devlation of Differences 8.77 8.84 Systolic Blood Pressure Pulse (beats/min)
