Question

1) You compare the height (cm) and weight (kg) of 5 adult women. You get the following results:
height 152.4 170.2 157.5 177.8 167.6
weight 54.0 64.9 59.4 70.3 61.7
(a) Construct a scatter plot of height (x) vs. weight (y)
(b) Calculate the following (show your work for SScp):
SSx SSy SScp ̄x ̄y
(c) Calculate the correlation coefficient (r)
2) Use the information from problem 1. Perform a complete test of the hypothesis that the population
correlation coefficient (ρ) is 0. Show all steps (note - obviously this should be a one sided test! Make sure you
know why!).
