Multiple Choice

Suppose you will perform a test to determine whether there is sufficient evidence to support a claim of a linear
correlation between two variables. Find the critical values of r given the number of pairs of data n and the significance
level $\alpha$
-Based on the data from six students, the regression equation relating number of hours of preparation (x) and test score $( \hat { y } )$ is $\mathrm { y } = 67.3 + 1.07 \mathrm { x }$ . The same data yield $\mathrm { r } = 0.224$ and $\overline { \mathrm { y } } = 75.2$ . What is the best predicted test score for a student who spent 2 hours preparing for the test?

• A) 78.1
• B) 75.2
• C) 59.7
• D) 69.4
