Question

A professor teaches two sections of an introductory statistics course. He gives each section the same final and wonders if any significant differences exist between the medians of these sections. He draws a sample of seven scores from Section A and six scores from Section B. Section A Section B 75 62 87 93 74 7765 64 95 72 7885 80 Cli Click here for the Excel Data File o. Set up the hypotheses to test the claim that the median test score in Section A differs from the median test score in Section B. Ho -2 05 HA: - 2 Ho: m1- 2 2 HA: - b-1. Use the appropriate software to conduct the relevant nonparametric test. The p-value corresponding to this test is: O p-value<0.01 0.01 s p-value<0.025 0 0025 S pvalue < 005 0.05 s p-value<0.10 p-value 2 0.10 b-2. At the 5% significance level, do the median test scores differ? O Yes, since we reject He O Yes, since we do not reject He- No, since we reject Ho No, since we do not reject H0.

Answer 1

Rank Type Score 75 62 87 93 12 2 13 4 95 72 10 85 sample size n1 sample size n2 Rank sum (R1)- Rank sum (R2)- 45

for b-1) p value >=0.10 (rest of the options are correctly selected)
