Systolic Blood Pressure Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury (mm Hg) and the standard deviation is 5.6. Assume the variable is normally distributed. Round the answers to at least 4 decimal places and intermediate z-value calculations to 2 decimal places. If a sample of 24 adults is randomly selected, find the probability that the sample mean will be between 117.4 and 120 mm Hg. Assume that the sample is taken from a large population and the correction factor can be ignored.

Step 1
We are given that the mean systolic blood pressure of normal adults is 120 mm Hg, and the standard deviation is 5.6 mm Hg. So, μ = 120 and σ = 5.6. Show more…

Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury (mm Hg ) and the standard deviation is 5.6 . Assume the variable is normally distributed. Round the answers to at least 4 decimal places and intermediate z -value calculations to 2 decimal places. If an individual is selected, find the probability that the individual's pressure will be between 119 and 122.8 mm Hg.

Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury (mmHg) and the standard deviation is 5.6. Assume the variable is normally distributed. Round the answers to at least 4 decimal places and intermediate z-value calculations to 2 decimal places. If a sample of 32 adults is randomly selected, find the probability that the sample mean will be between 118.2 and 121.2 mmHg. Assume that the sample is taken from a large population and the correction factor can be ignored.
