1. Below is data on the height and weight of a group of males. Compute the correlation coefficient for this data. Is there a relationship that exists between their height and their weight? Is the relationship positive or negative? Do you a rough scatterplot of the data. Does this confirm what you found computing the correlation? What is the critical value of r for a significance level of .05 one tail test? Does your calculation mean that that the computation is statistically significant?

Ht (in inches)	WT (in pounds)
67	140
71	165
73	168
71	142
74	200
68	135
71	150
69	168
66	106

2. Using the data from question 1 and assuming that all conditions are met for linearity, identify the independent (predictor), the dependent (response) variable. Compute the slope and the intercept. What would you predict the value of y to be for an x value of 70?
