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 =0.05.

Shoe Print (cm)	29.4	29.4	32.2	32.6	26.5
Foot Length (cm)	26.0	26.0	27.9	27.1	26.0
Height (cm)	180.3	175.3	187.7	180.1	178.5

Questions:

1. Construct a scatterplot.

2. The linear correlation is r= ________________ (round to three decimal place as needed.)

3. Determine the null and alternative hypotheses. H0:p _____ 0, H1:p= ________ 0

4. The test statistic is t= __________________ (round to two decimal places as needed.)

5. The P-value is _________________ (round to three decimal places as needed.)

6. Becasue the P-value of the linear correlation coefficient is ____________________ the significance level, there is _______________ sufficient evidence to support the claim that there is a linear correlation between shoe print lengths and heights of males.

7. Based on these results, does it appear that police can use a shoe sprint length to estimate the height of a male?
