Would I use the 13.1 for the sigma, and 140 for the lower boundary? Or does the central limit theorem apply here, and how would that look if the sample size is just one? I know part b calls for the simple size increasing to four, how would these look with staying in the parameters of bell curves and normalcdf operations?

1. For women aged 18 - 24, systolic blood pressure (in mm Hg) are normally distributed with a mean of 1 14.8 and a standard deviation of 13.1 (based on data from the National Health Survey). Hypertension is commonly defined as a systolic blood pressure above 140. (a) If a woman between the ages of 18 and 24 is randomly selected, find the probability that her systolic blood pressure is greater than 140. Draw and Label. PCX 7/40 M = 1 14-8 140 5= 13.1 (b) If 4 women in that age bracket are randomly selected, find the probability that their mean systolic blood pressure is greater than 140? Draw and Label. (c) Given that part (b) involves a sample size that is not larger than 30 why can the central limit theorem be used? 15 30 or nesmells Because it is normells distributed distributed
