There is a moderate relationship as rc = 0.5 ⦁ ⦁ The direction of the relationship is positive. As the correlation coefficient is positive. ⦁ What is the r critical for this particular sample (two tailed; alpha: .05)? rc= 0.878 ⦁ Is this a significant relationship based on the standard for rejecting the null hypothesis? since the null hypothesis is not rejected we have no evidence that there is a significant relationship. ⦁ Draw a scatter plot of the data listed.
