Question

If we are interested in testing whether the proportion of items in population 1 is larger than the proportion of items in population 2, what type of test should we use?

1) One-sample t-test
2) Two-sample t-test
3) Chi-square test
4) Z-test

Answer 1

To test whether the proportion of items in population 1 is larger than the proportion of items in population 2, we should use a Z-test. A Z-test is used when comparing proportions from two independent samples.

Step-by-step explanation:

To test whether the proportion of items in population 1 is larger than the proportion of items in population 2, we should use a Z-test. A Z-test is used when comparing proportions from two independent samples. It compares the sample proportions to determine if there is a significant difference between the population proportions.
