Question:

(a) Does the 95 percent confidence interval for the slope include zero? If so, what does this tell you? If not, what does it mean?
(b) Do a two-tailed t test for zero slope at α = .05. State the hypotheses, degrees of freedom, and critical value for your test.
(c) Interpret the p-value for the slope.
(d) Did the sample support your hypothesis about the sign of the slope?
