Compare the results from the sign test

Reference no: EM131397001

In Problem 1, the null hypothesis of equal weight of the male and female mice was tested using the t test. Use the exact sign test with α = .05. Compare the results from the sign test with those from the t test.

Problem 1
In Problem 2, test whether male rats are heavier, on average, than female rats. Use α = .05.

Problem 2
Mice from 12 litters were weighed when 4 months old, with one male and one female weighed from each litter. Weight in grams was recorded as follows:

Litter Number	Male	Female
1	26.0	16.5
2	20.0	17.0
3	18.0	16.0
4	28.5	21.0
5	23.5	23.0
6	20.0	19.5
7	22.5	18.0
8	24.0	18.5
9	24.0	20.0
10	25.0	28.0
11	23.5	19.5
12	24.0	20.5

Give a 95% confidence interval for the difference between the mean weight of male mice and female mice using a statistical program.
