You wish to display the factory’s relationship between hours
worked and number of combat vests delivered...
- You wish to display the factory’s relationship between hours
worked and number of combat vests delivered each month with a
simple linear best-fit equation where Y is equal to the number of
combat vests delivered.
The following chart gives a five-week
view of the situation.

- Which is the dependent variable? Vests
Delivered
- What is the range of the independent variable?
- Calculate the R-squared value for the relationship between the
hours worked and the vests delivered. What is the
R-squared value?
- What are the alpha .05 and the alpha .01 critical values for
the R-squared?
- How confident are you of a possible correlation between hours
worked and vests delivered?
- What percent of the relationship between hours worked and vests
delivered could be explained with a best fit equation?
- What is the best-fit linear equation?
- How many additional vests are produced for each hour
worked?
