For women aged 18-24, systolic blood pressures are normally distributed with a mean of 114.8 mm hg and a standard deviation of 13.1 mm hg. if 23 women aged 18-24 are randomly selected, find the probability that their mean systolic blood pressure is between 119 and 122 mm hg. round to four decimal places.

0.0579 is the probability that mean systolic blood pressure is between 119 and 122 mm Hg for the sample.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 114.8 mm Hg

Standard Deviation, σ = 13.1 mm Hg

Sample size = 23

We are given that the distribution of systolic blood pressures is a bell shaped distribution that is a normal distribution.

Formula:

Standard error due to sampling:

P(blood pressure is between 119 and 122 mm Hg)

0.0579 is the probability that mean systolic blood pressure is between 119 and 122 mm Hg for the sample.
