Question

Suppose that the mean systolic blood pressure for women over age seventy is 132 mmlig (millimeters of mercury), with a standard deviation of 7 mmHg. Suppose that the blood pressures are normally distributed Complete the following statements (a) Approximately? mmlig and 139 mmHg. . of women over seventy have blood pressures between 125 (b) Approximately 95% of women over seventy have blood pressures between and mm mmHg 1 x 5 ?

Answer 1

From the data given in the question:

• Approximately 65% of women over seventy have a blood pressure between 125 mmHg and 139 mmHg
• Approximately 95% of women over seventy have a blood pressure between and 118 mmHg and 146 mmHg.

The mean value for systolic blood pressure is 132 mmHg and with a standard deviation of 7 mmHg. So, the proportion of women who have a blood pressure between 125 mmHg and 139 mmHg is

P (125 < x < 139)

125 = 132-7

139 = 132 + 7

By empirical rule, about 68% of the data lies within 1 standard deviation of the average of about 68% of women.

132 - 2*7 = 118

132 + 2*7 = 146

About 95% of women over 70 years have a bp between 118 mmHg and 146 mmHg.
