Question

Find the critical values of r using is there sufficient evidance to conclude that there is a linear correlation

Answer 1

Answer:

Critical Values for the correlation coefficient r

Consult the table for the critical value of v = (n - 2) degrees of freedom, where n = number of paired observations. For example, with n = 28, v = 28 - 2 = 26, and the critical value is 0.374 at a = 0.05 significance level.

The statistical significance of the correlation.A statistically significant correlation is indicated by a probability value of less than 0.05. This means that the probability of obtaining such a correlation coefficient by chance is less than five times out of 100, so the result indicates the presence of a relationship.
