Assume that the mean systolic blood pressure of normal adults is 125 milliliters of mercury (mL Hg) and the standard deviation is 5.9. Assume the variable is normally distributed. If a sample of 30 adults is randomly selected, find the probability that the individual's pressure will be between 123 and 127.5 mL Hg. Please show all work below, showing how you got to your answer.
