When comparing two independent population means by using small samples selected from two independent normally distributed populations with equal variances,the correct test statistic to use is ____. A)Z B)t C)F D)t²

Question

Quizplus · Accepted Answer

When comparing two independent population means with small sample sizes, the correct test statistic to use is the t-test. The t-test takes into account the sample sizes and the sample standard deviations to determine the significance of the difference between the means. The Z-test is used when the population standard deviation is known, which is not the case in this scenario. The F-test is used for comparing variances of two populations, which is not the case here either. The option D is not a recognized test statistic.
