According to the text,hypotheses related to differences in population means if the population variance is unknown can be tested using the ________.
A) F distribution
B) p distribution
C) t distribution
D) z distribution
E) chi-square distribution

Question

Quizplus · Accepted Answer

When the population variance is unknown, the t-distribution should be used to test hypotheses related to differences in population means. The t-distribution is a family of distributions that varies depending on the sample size and degrees of freedom. It is similar in shape to the normal distribution but has heavier tails and a lower peak. The F distribution is used for testing hypotheses related to variances, while the z distribution is used when the population variance is known and the sample size is large. The p distribution and chi-square distribution are not appropriate for testing hypotheses related to differences in population means.
