t test: degrees of freedom, sum of squared deviations values and value of t

Correlation analysis: sum of x column, sum of y column, sum of x2 column, sum of y2 column, sum of xy column and value of r

Regression: sum of x column, sum of y column, sum of x2 column, sum of xy column and value of b, value of a.

Question (10 marks)

You work with couples who are experiencing marital stress as a result of one of them having Depression.
