The following two samples were collected as matched pairs. complete parts (a) through (d) below. pair 1 2 3 4 5 6 7 sample 1 6 7 10 4 6 8 9 sample 2 3 5 4 5 5 5 5 a. state the null and alternative hypotheses to test if a difference in means exists between the populations represented by samples 1 and 2. let mud be the population mean of matched-pair differences for sample 1 minus sample 2. choose the correct answer below. calculate the appropriate test statistic and interpret the results of the hypothesis test using a = 0.01.the test statistic is . (round to two decimal places as needed.) test statistics for this problem !
