A paired-difference experiment wasconducted to compare two populations. Thedata are shown in the table. Use a sign test to determinewhether the population distributions are different.PairsPopulation 1 2 3 4 5 6 71 8.9 8.1 9.3 7.7 10.4 8.3 7.42 8.8 7.4 9.0 7.8 9.9 8.1 6.9a. State the null and alternative hypotheses for thetest.b. Determine an appropriate rejection region witha .01.c. Calculate the observed value of the test statistic.d. Do the data present sufficient evidence to indicatethat populations 1 and 2 are different?
