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 ofr. 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 a = 0.05. Shoe Print (cm) | 29.4 Foot Length (cm) 24.8 Height (cm) 27.4 D 24.4 29.4 31.5 27.5 188.5 31.9 25.6 26.0 176.7 175 181.5 167.2 ..... Construct a scatterplot. Choose the correct graph below. OB. C.
