Hello,

Can someone please help e understand these questions; step-by-step process to understand how to solve these problems in the future?

A regression model between sales (yin $1000), unit price (x₁in dollars), and television advertisement (x₂in dollars) resulted in the following function:

= 7 - 3x₁+ 5x₂

For this model, SSR = 3500, SSE = 1500, and the sample size is 18.The coefficient ofx₂indicates that if television advertisement is increased by $1 (holding the unit price constant), sales are expected to?

a. decrease by $2000.

b. increase by $5000.

c. increase by $12,000.

d. increase by $5.

For this model, SSR = 3500, SSE = 1500, and the sample size is 18.To test for the significance of the model, the test statistic F is?

a. 2.33.

b. 1.75.

c. 17.5.

d. .70.

For this model, SSR = 3500, SSE = 1500, and the sample size is 18.To test for the significance of the model, the p-value is?

a. greater than .10.

b. between .025 and .05.

c. between .01 and .025.

d. less than .01.

For this model, SSR = 3500, SSE = 1500, and the sample size is 18.The adjusted multiple coefficients of determination for this problem is?

a. .8367.

b. .2289.

c. .70.

d. .66.
