Based on data from the National Health Survey, women between the ages of 18 and 24 have an average systolic blood pressures (in mm Hg) of 114.3 with a standard deviation of 12.09 . Systolic blood pressure for women between the ages of 18 to 24 follow a normal distribution. (a) If one woman from this population is randomly selected, find the probability that her systolic blood pressure is greater than 114 . Round your answer to four decimal places. P(x>114)= (b) If 60 women from this population are randomly selected, find the probability that their mean systolic blood pressure is greater than 114 . Round your answer to four decimal places. P(xˉ>114)= (c) If the sample were four women between the ages of 18 to 24 and we did not know the original distribution, could the central limit theorem be used? Yes or No?
