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) below. Male 15 comma 974 26 comma 598 1381 7732 19 comma 399 15 comma 474 14 comma 153 26 comma 609 Female 23 comma 948 13 comma 839 18 comma 810 17 comma 408 13 comma 149 16 comma 801 16 comma 434 18 comma 573 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, mu Subscript d 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? Upper H 0: mu Subscript d equals 0 word(s) Upper H 1: mu Subscript d less than 0 word(s) (Type integers or decimals. Do not round.) Identify the test statistic. tequals nothing
