Where is the F-distribution used?
OPTIONS
- To model discrete data when the population size is small compared to the sample size
- To make decisions and construct confidence intervals by summing the square of normal random variables
- To test for equality of variances from two normal populations
- To compensate for error in the estimated standard deviation for a small sample size
ANSWER
To test for equality of variances from two normal populations
EXPLANATION
Answer A aligns with the geometric and hypergeometric distributions. Answer D is partial explanation of the T-Distribution. Answer B is one description of the chi-square distribution.
