Question
Classify the two given samples as independent or dependent. Pre-training weights of 19 people Post-training weights of the same 19 people A)dependent B) independent As part of a marketing experiment, a department store regularly mailed discount coupons to 25 of its credit card holders. Their total credit card purchases over the next three months were compared to the credit card purchases over the next three months for 25 credit card holders who were not sent discount coupons. Determine whether the samples are dependent or independent. A) dependent B) independent Classify the two given samples as independent or dependent. The scores of 21 students who took the ACT The scores of 21 different students who took the SAT A)dependent B) independent True or False? In a one-way analysis of variance test with three independent samples, the following null and alternative hypotheses are appropriate: H_0: mu_1 = mu_2 = mu_3 H_a: mu_1 notequalto mu_2 notequalto mu_3 A) true B) false Which test is used to compare the population means of three or more populations? A) 2-sample t-test B) T-test on the differences C) ANOVA D) x^2 test E) None of theseExplanation / Answer
1) This is a dependent sample, as the same set of 19 people were used pre and post training
2) This is independent sample, as 25 people selected were not the same
3) This is again independent , as different students were slected based on exams ACT and SAT
4) True ,
1 way anova tries to measure if the mean between the groups are same or not , though they do not tell which groups are different
5)
we can use anova to measure the population means of 3 or more populations.
