The mean cholesterol level of women age 45-59 in Ghana, Nigeria, and Seychelles is 5.1 mmol/l and the standard deviation is 1.0 mmol/l. Assume that cholesterol levels are normally distributed. Round the probabilities to four decimal places. It is possible with rounding for a probability to be 0.0000. a) State the random variable. rv X = the mean cholesterol level of all women age 45-59 in Ghana, Nigeria, and Seychelles b) Find the probability that a randomly selected woman age 45-59 in Ghana, Nigeria, or Seychelles has a cholesterol level of 2.1 mmol/l or more. c) Find the probability that a randomly selected woman age 45-59 in Ghana, Nigeria, or Seychelles has a cholesterol level of 7.6 mmol/l or less. d) Find the probability that a randomly selected woman age 45-59 in Ghana, Nigeria, or Seychelles has a cholesterol level between 2.1 and 7.6 mmol/l. e) Find the probability that randomly selected woman age 45-59 in Ghana, Nigeria, or Seychelles has a cholesterol level that is at least 8.6 mmol/l. 0.0002 f) is a cholesterol level of 8.6 mmol/l unusually high for a randomly selected woman age 45-59 in Ghana, Nigeria, or Seychelles? Why or why not? g) What cholesterol level do 77% of all women age 45-59 in Ghana, Nigeria, and Seychelles have less than? Round your answer to two decimal places in the first box.
