6.) The mean cholesterol levels of women age 45-59 in Ghana, Nigeria, and Seychelles mmol/1 and the standard deviation is 1.0 mmol/1 (Lawes, Hoorn, Law & Rodgers, 2004 that cholesterol levels are normally distributed. a.) State the random variable. b.) Find the probability that a woman age 45-59 in Ghana has a cholesterol level above mmol/1 (considered a high level). c.) Suppose doctors decide to test the woman's cholesterol level again and average the values. Find the probability that this woman's mean cholesterol level for the two tests i 6.2 mmol/1. d.) Suppose doctors being very conservative decide to test the woman's cholesterol lev time and average the three values. Find the probability that this woman's mean cholest for the three tests is above 6.2 mmol/1. e.) If the sample mean cholesterol level for this woman after three tests is above 6.2 mmol/1, what could you conclude
