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 or = 0.05. Shoe Print (cm) 30.5 30.5 30.4 30.9 28.0 CI Foot Length (cm) 26.5 25.7 28.0 26.4 25.5 Height (cm) 173 179.9 182.9 168.9 177.9 E> Determine the null and alternative hypotheses. H0: p = 0 H1: p a 0 (Type integers or decimals. Do not round.) The test statistic is t= |:| (Round to two decimal places as needed.)
