A multiple regression analysis was conducted to predict quality (score between 1 and 10) based on alcohol (x₁), sulfates (x₂) and pH (x3). The parameter estimate table is below. Predict the quality when alcohol equals 9.07, sulfates equals 0.49 and pH equals 3.37. Term Intercept alcohol sulphates pH Estimate 3.3445 0.3668 0.8681 -0.6353 Round your answer to two decimal places. StErr T Ratio

In a regression analysis if SSE = 64 and SSR = 364, then what is the coefficient of determination? (please keep 2 decimal places)

The linear regression equation for predicting systolic blood pressure from age is: y = 54 + 1.6*x Find the residual for a person who is 32 years of age with a systolic blood pressure of 103.9 (round your answer to one decimal place)

The slope, b represents * O predicted value of Y when X = 0. O the estimated average change in Y per unit change in X. O variation around the line of regression. O the predicted value of Y.

To see how the brain expresses empathy, researchers recruited 16 couples in their midtwenties who were married or had been dating for at least two years. They zapped the man's hand with an electrode while the woman watched, and measured the activity in several parts of the woman's brain that would respond to her own pain. Brain activity was recorded as a fraction of the activity observed when the woman herself was zapped with the electrode. The women also completed a psychological test that measures empathy.
