Answer #1

The following are body mass index scores measured in 12
patients who are free of diabetes and participating in a study of
risk factors for obesity. body mass index is measured as the ratio
of weight in kilograms to height in meters squared. Using the
following data, compute the mean BMI, the standard deviation of
BMI, the median BMI and the Q1 and Q3. Are there outliers in the
distribution of BMI? Justify your answer.

You need to create two histograms: one for the pre-BMI intervention
and another for the post-BMI intervention.
Please
provide your interpretation of the results. For example, you might
want to compare

Suppose we want to do a study on the body mass index
(BMI) on patients who are free of diabetes and participating in a
study of risk factors for obesity. Body mass index is measured as
the ratio of weight in kilograms to height in meters
squared.
1. How many participants would be needed to ensure that a 95%
confidence interval estimate of BMI had a margin of error not
exceeding 2 units? Assume that the standard deviation of BMI...

Your body mass index (BMI) is your weight in kilograms divided
by the square of your height in meters. High BMI is a common but
controversial indicator of overweight or obesity. A study by the
National Center for Health Statistics found that the BMI of
American young men (ages 20-29) is approximately Normal with mean
25.8 and standard deviation 4.2. To have a BMI higher than 90% of
all men aged 20-29, what would your BMI would need to be?

A researcher conducted a study on mindfulness and body mass
index (BMI). She collected BMI scores from a large group of
participants who had completed a mindfulness training program and
then compared their scores to the national average BMI scores from
the general population. What type of test should be used to see if
taking the mindfulness program was beneficial for BMI scores
not?

One-sample t test
Dependent-means (paired-samples) t test
Independent-means (Independent-samples) t test
