An experiment was designed to estimate the mean difference in weight gain for pigs fed ration A as compared with those fed ration B. Eight pairs of pigs were used. The pigs within each pair were littermates. The rations were assigned at random to the two animals within each pair. The gains (in pounds) after 45 days are shown below:

RationA	RationB
65	58
37	39
40	31
47	45
49	47
65	55
53	59
59	51

Assuming weight gain is normal, find the 95% confidence interval estimate for the mean of the differences μ_d where d= ration A - ration B.
