1. A
researcher is interested to learn if there is a linear relationship between the
hours in a week spent exercising and a persons life satisfaction. The
researchers collected the following data from a random sample, which included
the number of hours spent exercising in a week and a ranking of life
satisfaction from 1 to 10 ( 1 being the lowest and 10 the highest).

2. Find
the mean hours of exercise per week by the participants.

3. Find
the variance of the hours of exercise per week by the participants.

4. Determine
if there is a linear relationship between the hours of exercise per week and
the life satisfaction by using the correlation coefficient.

5. Describe
the amount of variation in the life satisfaction ranking that is due to the
relationship between the hours of exercise per week and the life satisfaction.

6. Develop
a model of the linear relationship using the regression line formula.
