**Question 20**

When individuals in a sample of 150 were asked whether they supported capital punishment, the following information was obtained:

- **Do you support capital punishment? Number of individuals**
  - Yes: 45
  - No: 55
  - No Opinion: 50

We are interested in determining whether or not the opinions of the individuals (as to Yes, No, and No Opinion) are uniformly distributed. The calculated value for the test statistic equals:

- a. 2
- b. -2
- c. 1
- d. 4

**Question 21**

In simple linear regression, \( r^2 \) is the:

- a. mean square error.
- b. correlation coefficient.
- c. squared residual.
- d. coefficient of determination.
