# Question: A set of n 20 pairs of scores X

A set of n = 20 pairs of scores (X and Y values) has SSX = 16, SSY = 100, and SP = 32. If the mean for the X values is MX = 6 and the mean for the Y values is MY = 20,

a. Calculate the Pearson correlation for the scores.

b. Find the regression equation for predicting Y from the X values.

a. Calculate the Pearson correlation for the scores.

b. Find the regression equation for predicting Y from the X values.

A set of n = 25 pairs of scores (X and Y values) produces a regression equation of Yˆ = 3X – 2. Find the predicted Y value for each of the following X scores: 0, 1, 3, –2. Problem 9 examined the relationship between weight and income for a sample of n = 10 women. Weights were classified in five categories and had a mean of M = 3 with SS = 20. Income, measured in thousands, had a mean score of ...With a small sample, a single point can have a large effect on the magnitude of the correlation.
