Question 2
1.
If you wanted to analyze the correlation between the NUMBER OF HOURS PRACTICED and the NUMBER OF TARGETS HIT by a sharpshooter, which variable would be the dependent variable?

[removed]

Number of hours practiced

[removed]

Number of targets hit

[removed]

Neither one is dependent

[removed]

Either one could be dependent (impossible to determine)

Question 3
1.
Before proceeding with a simple linear regression, you should first construct a scatter diagram in order that you can remove all outliers from the data.
[removed]True
[removed]False
10 points
Question 4
1.
What does it mean to have a negative coefficient in the regression model?

[removed]

That variable reduces the coefficient of determination.

[removed]

The values for that variable are negative.

[removed]

There is an inverse relationship with that variable.

[removed]

The correlation is weak.

10 points
Question 5
1.
Assuming a linear relationship between X and Y, if the coefficient of correlation (r) equals -0.30,

[removed]

there is no correlation.

[removed]

the slope (b1) is negative.

[removed]

variable X is larger than variable Y.

[removed]

the variance of X is negative.

10 points
Question 6
1.
If the hypothesis test for correlation is found to be significant (i.e., we rejected the null hypothesis / accepted the alternate hypothesis), what can we automatically conclude about the strength of the correlation?

[removed]

We can conclude that the correlation must be strong.

[removed]

We can only conclude that the correlation is not weak

[removed]

We cannot conclude anything about the strength of the correlation yet.

Question 7
1.
A negative correlation coefficient implies that as the value of independent variable increases, the value of the dependent variable _________________.

[removed]

Increases

[removed]

Decreases

[removed]

Cannot be determined from the information given

Question 8
1.
There is a strong positive correlation between a baby’s weight and the size of his/her vocabulary. From this we can conclude that overeating will improve one’s vocabulary.
[removed]True
[removed]False

Question 9
1.
If the correlation coefficient (r) = 1.00, then

[removed]

all the data points must fall exactly on a straight line with a slope that equals 1.00.

[removed]

all the data points must fall exactly on a straight line with a negative slope.

[removed]

all the data points must fall exactly on a straight line with a positive slope.

[removed]

all the data points must fall exactly on a horizontal straight line with a zero slope.

Question 10
1.
Assume the regression model for predicting home prices by the square footage were: PRICE = 12510 + 83 (SQRFT) For every additional one square foot, how much does the price increase?

[removed]

\$12,593

[removed]

\$83

[removed]

\$166

[removed]

Cannot be determined from the information given.
