A company is testing two breeds of rabbits to determine which one is more productive under a feeding scheme that includes direct grazing in open pastures. Ten rabbits of each variety are raised in independent pastures. Variety X yields an average of 1.5 kg clean carcass with a sample standard deviation of 0.20 kg. Variety Y yields 1.7 kg with standard deviation of 0.25. Assume that the population variances for X and Y are equal, test the hypothesis that the yields are equal. Part A. What is the null hypothesis?

Solution

Here, the null hypothesis is, if uX and uY are the means of groups X and Y,

Ho: uX - uY = 0 [ANSWER]
