Hlst 2300 fall exam review: the mean body mass index (bmi) for boys age 12 is 23. 6. Bmi is higher in 12-year-old boys living in new york city. Assume that the standard deviation in bmi is 5. 7: suppose we want to estimate the mean bmi for women in pregnancy at 20 weeks gestation. If we have a sample of 100 women and measure their bmi at 20 weeks gestation, what is the probability that the sample mean is within 1 unit of the true bmi if the standard deviation in. Bmi is taken to be 3. 6: an experimental drug has been shown to be 75% effective in eliminating symptoms of allergies in animal studies. A small human study involving 6 participants is conducted. Find the following: the proportion of women with bmi> 30, the proportion of women with bmi>40, the bmi that separates the top 10% from the rest, investigators want to assess the accuracy of self-reported smoking status.
