The weight and systolic blood pressure of 30 randomly selected males in the age group 25-30 are shown below. Assuming that weight and blood pressure (BP) are normally distributed. a) Find a regression line relating systolic blood pressure wo weight b) Estimate the coefficient of determination and interpret your findings c) Test the hypothesis that p-0 d) Test the hypothesis that p-0.6. e) Find the 95% CI for p ) Consider the weight and blood pressure and fit a non-intercept model to the data and compare it to the model obtain in part (a). which model would you consider superior?
