Listed below are the numbers of words spoken in a day by each member of eight different randomly selected couples. complete parts a) and b) Male 15,585 27,149 1417 7504 18,232 16,059 13,929 26,128 Female 24,630 13,872 18,097 17,504 13,480 16,833 16,382 18,222 a. Use a 0.01 significance level to test the claim that among couples, males speak fewer words in a day than females. In this example, μd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the words spoken by the male minus words spoken by the female. What are the null and alternative hypotheses for the hypothesis test? a) identify the test statistic, t? identify the p value? b)construct the confidence interval that could be used for the hypothesis test described in part (a)
