Draw the scatterplot of the response CSpd versus the predictor RSpd. Is the simple linear regression model plausible for these data?

Fit the simple regression of the response on the predictor, and present the appropriate regression summaries.

Obtain a 95% prediction interval for CSpd at a time when RSpd = 7.4285.
