Transcribed Image Text:Police sometimes measure shoe prints at crime scenes so that they can learn something about criminals. Listed below are shoe print lengths, foot lengths, and heights
of males. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value of r. Determine whether there is sufficient evidence to support
a claim of linear correlation between the two variables. Based on these results, does it appear that police can use a shoe print length to estimate the height of a male?
Use a significance level of α = 0.01.
Shoe Print (cm)
Foot Length (cm)
Height (cm)
Height (cm)
