(Round your answer to two decimal places.) mg/dL 120 140 160 180 200 220 240 What is the approximate standard deviation of the LDL cholesterol levels? (Round your answer to two decimal places.) mg/dL
(c) What is the approximate proportion of the LDL cholesterol levels that is within one standard deviation of the mean? (Use the empirical rule. Round your answer to the nearest whole number.) % (d) What is the approximate proportion of the LDL cholesterol levels that is more than two standard deviations above the mean? (Use the empirical rule. Round your answer to one decimal place.) % (e) What is the range of LDL cholesterol levels within two standard deviations of the mean? (Round your answers to two decimal places.) mg/dL to mg/dL B (f) LDL cholesterol levels of about 150 mg/dL and above are considered to be borderline high to very high levels. Determine if high LDL cholesterol levels are only associated with weights of 200 lb and above. O Yes, high LDL cholesterol levels are only associated with weights of 200 lb and above. O No, high LDL cholesterol levels are only associated with weights of 220 lb and above. O No, high LDL cholesterol levels appear to occur with all weights between 120 lb and 220 lb. O No, high LDL cholesterol levels are only associated with weights of 140 lb and below. O No, high LDL cholesterol levels appear to occur with all weights between 100 lb and 240 lb. (g) LDL cholesterol levels less than 100 mg/dL are considered to be optimal levels. Determine if optimal LDL cholesterol levels are only associated with weights of 160 lb and below. O Yes, optimal LDL cholesterol levels are only associated with weights of 160 lb and below. O No, optimal LDL cholesterol levels appear to occur with all weights between 100 lb and 240 lb. O No, optimal LDL cholesterol levels are only associated with weights of 160 lb and above. O No, optimal LDL cholesterol levels are only associated with weights of 140 lb and below. O No, optimal cholesterol levels appear to occur with all weights between 100 lb and 160 lb and between 180 lb and 240 lb.
