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 bn 1 = 1.1909, s = 3.0018, SSxy = 370.9, and r@value = .0000607.

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.

b. Make an appropriate conclusion for your analysis.

c. Construct a 95% confidence interval for the slope parameter. Interpret your result.
