Systolic Blood Pressure 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. Part 1 of 3 If an individual is selected, find the probability that the individual's pressure will be between 117.3 and 120 mmHg. P(117.3 < X < 120) = 111 Part: 1/3 - Part 2 of 3 If a sample of 28 adults is randomly selected, find the probability that the sample mean will be between 117.3 and 120 mmHg. Assume that the sample is taken from a large population and the correction factor can be ignored. P(117.3 < X < 120) = Next Part olo Submit Assignment 2020 meoraw Thill LLC. All Rights Reserved.
