In men, 90% of BMIS are below 36.7, and 95% of BMIS are below 38.9. In women, 90% of BMIS are below 37.0, and 95% of BMIS UISTRIBUTION Excel can also be used to compute percentiles for the standard normal distribution and any normal distribution. The two rel- evant functions are NORMSINV and NORMINV, respectively. The inputs for the functions are shown below. Recall from Chapter 5 in the textbook that a percentile is a score that holds a specified percentage or proportion of scores below it. For ex- ample, the 80th percentile is the score that holds 80% of the scores below it. are below 39.5, 5.4 PRACTICE PROBLEMS 1. Total cholesterol in children aged 10-15 years is as- sumed to follow a normal distribution with a mean of 191 and a standard deviation of 22.4. a. What proportion of children 10-15 years of age have total cholesterol between 180 and 190? b. What proportion of children 10-15 years of age would be classified as hyperlipidemic (Assume that hyperlipidemia is defined as a total choles- terol level over 200)? ED The function to compute percentiles for the standard nor- mal distribution is used as follows: =NORMSINV(probability) The input for the function is the desired percentile, entered as a probability or proportion. For example, to compute the 80th or the 95th percentile, we specify 0.80 or 0.95, respectively. The function to compute percentiles for any normal dis- tribution is used as follows: c. What is the 9oth percentile of cholesterol levels? 2. Among coffee drinkers, men drink a mean of 3.2 cups per day, with a standard deviation of 0.8 cups. Assume OFocus
