Inference for two means

1. Jordan’s cat ?Fern? is a finicky eater. Jordan is trying to determine which of two brands of canned cat food Fern prefers, Tab-a-Cat or Chow Lion. For two months, she flips a coin each day to decide which of the two foods to feed Fern, and weighs how much Fern eats in grams. Here is the data:

Tabacat

31 n

85.2 xbar

3.45 s

Chowlion

30 n

82.1 xbar

4.62 s





Find the standard error for the difference in the mean amount of Tab-a-Cat that Fern eats and the mean amount of Chow Lion she eats.



(d) The test statistic is t = 2.962. Determine the P-value and draw an appropriate conclusion, using ? = 0.01
