The following results were obtained from a multiple regression model predicting Y from X_1 and X_2. Indicate whether each of the following statements is true or false:

Solution

a)

False. We need to square 0.39 first.

*****************

b)

FALSE. As P = 0.160 for x1, which is bis (>0.05), it is not significant.

**********************

c)

FALSE. The coefficient of x1 is negative, so it must be a DECREASE by 0.56 units.

********************

d)

FALSE. The intercept is 3.64.

******************

e)

FALSE. The P value is 0.016, which is small (<0.05). Thus, it is significantly different from 0.
