A health researcher wants to determine the effectiveness of a new blood pressure medication. As the
medicine is new, 37 respondents volunteered to try the medicine. The average blood pressure of the 37
respondents was 124mmHg with a standard deviation fo 10mmHg. Assume blood pressure is normally
distributed. Calculate a 95% confidence interval for the blood pressure range of any individual who is
prescribed the medicine.
O (120.78, 127.22)
O (120.67, 127.33)
