Diabetes and obesity are serious health concerns in the United States and much of the
developed world. Measuring the amount of body fat a person carries is one way to monitor
weight control progress, but measuring it accurately involves either expensive X-ray
equipment or a pool in which to dunk the subject. Instead body mass index (BMI) is often
used as a proxy for body fat because it is easy to measure: BMI = mass(kg)/(height(m))² = 703
mass(lb)/(height(in))².
In a study of 15 men at TXST, both BMI and body fat were measured. Researchers imported
the data into statistical software for analysis.
A few values are missing from the output. Complete the table by filling in the missing values.

Does a simple linear regression model seem reasonable in this situation?…
The use of electromyostimulation (EMS) as a
method to train healthy skeletal muscle is
studied. EMS sessions consisted of 30
contractions (4-second duration, 85 Hz) and
were carried out three times per week for three
weeks on 17 ice hockey players. The 10-meter
skating performance test showed a standard
deviation of 0.90 seconds. Is there strong
evidence to conclude that the standard deviation
of performance time exceeds the historical value
of 0.75 seconds? Use a = 0.05.
