2. For each situation below, provide the following: 2. sr, sample t ratio, critical t value, and the statistical decision regarding H0: ρ=0. (Assume that the obtained correlation is in the direction of H1.)

(a) r = 38, n=30, α= 05, two-tailed test

(b) r = 60, n= 10, α= 05, two-tailed test

(c) r = 17, n=62, α= 01, two-tailed test

(d) r = 69, n= 122, α= 05, one-tailed test

(e) r = 43, n=140, α= 01, one-tailed test
