(a) Suppose we want to use systolic blood pressure to predict diastolic blood pressure. The explanatory variable is and the response variable is (b) Describe the form, direction, and strength of the relationship: Form (Linear or Non-Linear) Direction (Positive or Negative) Strength (Weak or Moderate or Strong) (c) Find the value of the correlation coefficient between systolic blood pressure and diastolic blood pressure. (d) What percentage of the variation in diastolic blood pressure can be explained by systolic blood pressure? (e) Find an equation of the least-squares regression line for systolic blood pressure and diastolic blood pressure. (9 When I measured my blood pressure this morning, my systolic blood pressure was 121. Use the least-squares line to predict my diastolic blood pressure. (g) When my systolic blood pressure measured 121, my diastolic blood pressure reading was actually 77. Does the model overestimate, underestimate or accurately predict my diastolic blood pressure? (h) For what range of systolic blood pressure readings would it be appropriate to use this regression line equation to predict diastolic blood pressure (to avoid extrapolation)?

The basic hypothesis is that people who play sports are more likely than others to watch sport on TV. Your first task is to crosstabulate the data involving the playing and watching of sports and to determine the direction and strength of that relationship. Write out your findings about this basic relationship. Your next task is to determine the direction and strength of the partial relationships when you control for the gender of individuals.
