Answer to Problem T11.2SPT

Option e) is correct.

Explanation of Solution

Given:

I. Independent random samples from the populations of interest.

II. All sample sizes are less than 10% of the populations of interest.

III. All expected counts are at least 5.

Calculation:

The conditions for Chi-square test are: Random, Independent and Large counts.

Random: Independent random samples from the populations of interest.

Independent: All sample sizes are less than 10% of the populations of interest.

Large counts: All expected counts are at least 5.

All these are correct conditions. Hence option e is correct.
