2. For each of the following, determine whether the sample provides enough evidence to conclude that there is a significant, nonzero correlation in the population.  In each case, use a two-tailed test with α = .05.
For a two-tailed test with α = .05, critical value of r with df = 16 is ±0.468. r = -0.50 is less than -0.468. Thus, the sample provides enough evidence to conclude that there is a significant, nonzero correlation in the population. 
For a two-tailed test with α = .05, critical value of r with df = 13 is ±0.514. r = -0.50 is greater than -0.514. Thus, the sample does not provide enough evidence to conclude that there is a significant, nonzero correlation in the population. 
For a two-tailed test with α = .05, critical value of r with df = 28 is ±0.361. r = -0.375 is less than -0.361. Thus, the sample provides enough evidence to conclude that there is a significant, nonzero correlation in the population. 
For a two-tailed test with α = .05, critical value of r with df = 23 is ±0.396. r = -0.50 is less than -0.396. Thus, the sample provides enough evidence to conclude that there is a significant, nonzero correlation in the population.
