A sample of 25 individuals was taken to investigate the relationship between their annual income and number of years of education. The Pearson's correlation coefficient (r) was calculated to be 0.6. Test the hypothesis at a significance level of 0.01 that the population correlation coefficient is different from 0.
Even a very small effect can be significant if the sample is large enough. Suppose, for example, that a researcher obtains a correlation (computed from the raw data) of r = 0.60 for a sample of n = 10 participants. a. Is this sample sufficient to conclude that a significant correlation exists in the population? Use a two-tailed test with α = .05. In your response, be sure to specify the critical value for r. b. If the sample had n = 25 participants, is the correlation significant? Again, use a two-tailed test with α = .05. In your response, be sure to specify the critical value for r.

Suppose IQ scores were obtained for 20 randomly selected sets of couples. The 20 pairs of measurements yield x = 100.08, y = 99.15, r = 0.899, P-value =0.000, and y=−5.36+1.04x, where x represents the IQ score of the wife. Find the best predicted value of y given that the wife has an IQ of 98? Use a significance level of 0.05.
