Assume that the mean systolic blood pressure of normal adults is 120millimetersof 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 27 adults is randomly selected, find the probability that the sample mean will be between 120 and 122.2mmHg. Assume that the sample is taken from a large population and the correction factor can be ignor
