Answer #1

Answer:

d. an independent-samples t-test

Explanation:

From the given information, it is observed that the given data is not related or paired data. Both samples are independent. So, we can’t use related samples t test. Here, we have to compare two population means and we are given that variances are not homogeneous. So, we need to use an independent samples t-test. We consider the dependent variable productivity have ratio scale. If productivity measured in the ordinal scale, then we need to use other non-parameteric test which is an alternative for the independent samples t-test. If dependent variable is not ratio scaled, then we will need to use Mann-Whitney U test.
