1.Given the following circumstances, determine whether the calculated values of r are statistically significant:

a) r = .29, N = 35, = .01, two-tailed

b) r = .50, N = 15, = .05, two-tailed

c) r = .12, N = 500, = .05, two-tailed

d) r = .55, N = 12, = .05, one-tailed

e) r = .44, N = 26, = .01, one-tailed
