3) Ten pairs of variables x and y were collected to determine if there is sufficient evidence to indicate that x and y have a negative linear relationship at the 5% significance level. The regression analysis results in B, = 1.1909, s = 3.0018, SSxy = 370.9, and p-value = 0.0000607. [35 Points] a. Specify the null and alternative hypotheses to test whether the data provide sufficient evidence to indicate that x and y have a negative linear relationship. [10 Points] b. Make an appropriate conclusion for your analysis. [10 Points]- c. Construct a 95% confidence interval for the slope parameter. Interpret your result. [15 Points]
