Hi. I need help finding the linear correlation coefficient, test statistics, and p-value. Help please
The linear correlation coefficient is r=1 (Round to three decimal places as needed.) Determine the null and alternative hypotheses. Ho: P = 0 H₁: p0 (Type integers or decimals. Do not round.) The test statistic is t = (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.)

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) Construct a scatterplot. Choose the correct graph below. OA.
