# Project #82671 - Descriptive statistics and ANOVA

Scenario 1:
A researcher wants to determine if different forms of regular exercise alter HDL levels in obese middle aged males between the ages of 35 and 45.  Participants in the study are randomly assigned to one of four exercise groups  No Exercise, Resistance Training, Aerobic Exercise or Stretching/Yoga – and instructed to follow the program for 8 weeks.  Their HDL levels are measured after 8 weeks and are summarized below.

 Exercise Group N Mean Std Dev No exercise (TV watching 60 min/day) 40 45.1 9.8 Resistance Training 60min/day 40 51.2 10.2 Aerobic Exercise 60min/day 40 46.3 11.1 Stretching/Yoga 60min/day 40 47.1 12.5

1) What is the null hypothesis equation for this experiment?

2) Specify the νn numerator degrees of freedom? Please paste your data output file in the space below.

3) Specify the νd denominator degrees of freedom?

4) Identify the F-critical value at P<0.05 from the F distribution table 3-1 from the Primer of Biostatistics 7th Ed

5) Identify the F-critical value at P<0.01 from the F distribution table 3-1 from the Primer of Biostatistics 7th Ed

6) Specify whether you accept or reject the null hypothesis at P<0.05?

7) Specify whether you accept or reject the alternate hypothesis at P<0.05?

Scenario 2:
A researcher wants to determine if an experimental drug lowers Triglyceride levels (mg/dL) in individuals with elevated Triglycerides. (15pts)

17) What is the null hypothesis equation for this experiment?

18) What scale of measurement are Triglyceride levels (mg/dL)?
A) Nominal
B) Ordinal
C) Interval
D) Ratio

19) What is the F critical value at P<0.05

20) Specify whether you accept or reject the null hypothesis at P<0.05?
