Answer the following problem based on the concept of Linear Correlation and Regression. Do not round off to the process of computing it but on the answers on this, round off your answers based on the instructions given. Use the formula of Pearson for computing the value of r. 1. Police sometimes measure shoe prints at crime scenes so that they can learn a few things about criminals. Listed below are shoe print lengths and heights of females. Is there a sufficient evidence to conclude that there is a linear correlation between shoe print lengths and heights of females. Use alpha = 0.10. Shoe Print (cm) (x) Height (cm) (y) 26.5 167.6 26.0 165.1 27.0 172.7 25.1 157.5 27.9 167.6   a. Based on the problem, what is the value of the Pearson r?

Question

Answer the following problem based on the concept of Linear Correlation and Regression. Do not round off to the process of computing it but on the answers on this, round off your answers based on the instructions given.

Use the formula of Pearson for computing the value of r.

1. Police sometimes measure shoe prints at crime scenes so that they can learn a few things about criminals. Listed below are shoe print lengths and heights of females. Is there a sufficient evidence to conclude that there is a linear correlation between shoe print lengths and heights of females. Use alpha = 0.10.

Shoe Print (cm) (x) Height (cm) (y)
26.5 167.6
26.0 165.1
27.0 172.7
25.1 157.5
27.9 167.6

 

a. Based on the problem, what is the value of the Pearson r? [Round off to 4 decimal places.] If the answer is negative, make sure to also include the negative sign.

b. Based on the problem, what is the value of computed t? [Round off to 4 decimal places.] If the answer is negative, answer it already as a positive number.

c. Based on the problem, what is the value of the tabular value of t? [Type them as a whole at 3 decimal places.]
