Question
Use the shoe print lengths and heights shown below to find the regression equation, letting shoe print lengths be the predictor (x) variable. Then find the best predicted height of a male who has a shoe print length of
28.5
cm. Would the result be helpful to police crime scene investigators in trying to describe the male? Use a significance level of
α=0.05.

cm.(Round to two decimal places as needed.)
Would the result be helpful?
No, because the description would be the same regardless of shoe print length.
Yes, because the description would be based on an actual shoe print length.
Yes, because the correlation is strong, so the predicted height should be very accurate.
No, because the correlation is weak, so the predicted height would only be within
