Question

The total cholesterol levels of a sample of men aged 35-44 are normally distributed with a mean of 204 milligrams per deciliter and a standard deviation of 38.7 milligrams per deciliter (a) What percent of the men have a total cholesterol level less than 231 milligrams per deciliter of blood? (b) If 252 men in the 35-44 age group are randomly selected, about how many would you expect to have a total cholesterol level greater than 269 milligrams per deciliter of blood? (a The percent of the men that have a total cholesterol evel ess than 231 m 11 grams per deciliter of blood Round to two decimal places as needed) % (b) Of the 252 men selected, would be expected to have a total cholesterol level greater than 269 miligrams per deciliter of blood (Round to the nearest integer as needed.)

estimate the average age at which multiple sclerosis patients were diagnosed with the condition for the first time in a given city. How big should the sample be? Define your procedures for this estimate (if necessary, set your own values of unknown parameters, based on statistical theory). In Table 1 you will find all ages of this patient population. 54 58 56 48 62 59 55 56 60 52 53 61 56 56 53 37 71 62 39 61 54...
