Refer to Exercise 11.55. Is r = .8 big enough to claim ρ > 0 at the \(\alpha=.05\) significance level?
a Assume n = 5 and implement the test.
b Assume n = 12 and implement the test.
c Applet Exercise Determine the p-values for the tests implemented in parts (a) and (b).
d Did you reach the same conclusions in parts (a) and (b)? Why or why not?
e Why is the p-value associated with the test in part (b) so much smaller that the p-value associated with the test performed in part (a)?
