Question

Question 4

The norm for the Family Responsibility (FRE) scale of the California Psychological Inventory (CPI) is 32; those scoring higher than the norm are considered to be highly responsible. A researcher believes that the higher the number of children in the family (X), the higher the family responsibility (Y). To test this, the CPI/FRE was administered to a group of 10 adolescents from families of various sizes. They were found to have the following scores:

Child	1	2	3	4	5	6	7	8	9	10
sibs(X)	3	4	3	4	1	1	1	3	3	2
FRE(Y)	33	35	31	38	32	30	29	39	36	35

(1) Perform the hypothesis test for Ho: ρ<0 using .01 starting with the df = ?

Your critical value @ .01 = ?

Your calculated value for "r" = ?

(round your answer to two decimal places)

Answer 1

(1) DF = n-2 = 10-2 = 8
