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 litter-mates. The rations were assigned at random to the two animals within each pair. The gains (in pounds) after 45 days are shown in the following table. Assuming weight gain is normal, find the 99% confidence interval estimate for the mean of the differences ?d, where d = ration A - ration B. (Give your answers correct to two decimal places.) Litter 1 2 3 4 5 6 7 8 Ration A 63 57 64 51 45 43 44 48 Ration B 61 52 54 45 35 40 41 47 Lower Limit Upper Limit
Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
this was also answered wrong.

| Ration A | 63 | 57 | 64 | 51 | 45 | 43 | 44 | 48 |
| Ration B | 61 | 52 | 54 | 45 | 35 | 40 | 41 | 47 |
