Question
Which of the following is used to check the equality of proportions for 2 populations?
- a. ANOVA
- b. t-test
- c. f-test
- d. z-test
Solution
To determine which statistical test is used to check the equality of proportions for two populations, we can analyze the options given:
-
ANOVA (Analysis of Variance): This is used to compare means across three or more groups, not proportions.
-
t-test: This is used for comparing the means of two populations, not proportions.
-
f-test: This test is generally used to compare variances between two populations, not proportions.
-
z-test: This is specifically used to compare proportions for large sample sizes from two populations.
Final Answer
The correct answer is d. z-test.
