The Body Mass Index (BMI) is a value calculated based on the weight and the height of an individual. In a small European city, a survey was conducted one year ago to review the BMI of the citizens. In the sample with 200 citizens, the mean BMI was 23.3 kg/m2 and standard deviation was 1.5 kg/m2. It is reasonable to assume the BMI distribution is a normal distribution. (a) Find the point estimate of the population mean BMI one year...

A group of researchers developed a 95% z confidence interval for the mean body mass index (BMI) of women aged 20 to 29 years, based on a national random sample of 633 such women. They assumed that the population standard deviation was known to be σ = 7.5. In fact, the sample data had mean BMI x = 26.9 and standard deviation s = 7.55.

We have the survey data on the body mass index (BMI) of 659 young women. The mean BMI in the sample was x¯=25.5. We treated these data as an SRS from a Normally distributed population with standard deviation σ=7.8 . Give confidence intervals for the mean BMI and the margins of error for 90%, 95%, and 99% confidence.
