Multiple Choice

Use the following to answer the questions below:
Students in a small statistics course wanted to investigate if forearm length (in cm) was useful for predicting foot length (in cm) . The data they collected are displayed in the provided scatterplot (with regression) , and the computer output from the analysis is provided.
Use three decimal places when reporting the results from any calculations, unless otherwise specified.
‪
The regression equation is Foot (cm) = 9.22 + 0.574 Forearm (cm)
-What is the test statistic for a test of the slope? What is the p-value? What is the conclusion of the test, in context?

A) t = 3.63; p-value = 0.004
There is strong evidence that forearm length is a useful predictor of foot length.
B) t = 2.04; p-value = 0.066
There is not enough evidence to conclude that forearm length is a useful predictor of foot length.
C) t = 3.63; p-value = 0.004
There is not enough evidence to conclude that forearm length is a useful predictor of foot length.
D) t = 2.04; p-value = 0.066
There is strong evidence that forearm length is a useful predictor of foot length.
