She wondered if it is reasonable to claim that spouses were essentially the same age; in other words, was any difference between the ages of husbands and wives, at the 5% level of significance? The data she collected was as follows:

Husband	39	23	25	45	60	89	36	39	50	77
Wife	37	22	25	48	55	83	35	40	50	73

Husband	29	31	65	48	37	55	34	27	61	75
Wife	27	30	62	48	43	39	30	24	57	75

Husband	21	36	43	51	60	45	23	37	49	58
Wife	18	39	44	50	61	45	23	36	41	55
