- Compute r by hand and check your results with the calculator.
- Perform a t-test for the correlation coefficient using α = 0.05
- Find the linear regression model for this data. (Check a and b on your calculator.)
- Use your model to predict the Bowling average of a person with 12 years of experience.
- Use your model to predict the years of experience for a bowler with a 175 bowling average.

medical research using stem cells obtained from human embryos." Of
those polled, 485 were in favor, 402 were opposed, and 125 were
unsure. A politician claims that people don't really understand the
stem cell issue and their responses to such questions are random
responses equivalent to a coin toss. Exclude the 125 subjects who
