A national grocery store chain wants to test the difference in the average mass of turkeys sold in Guelph, Ontario, and the average mass of turkeys sold in Sudbury, Ontario. According to the chain’s analyst, a random sample of 20 turkeys sold at the chain’s stores in Guelph yielded a sample mean of 7.97 kg, with a standard deviation of 1.5 kg. Her random sample of 24 turkeys sold at the chain’s stores in Sudbury yielded a sample mean of 6.7 kg, with a standard deviation of 1.2 kg. Use a 1% level of significance to determine whether there is a difference in the mean mass of turkeys sold in these two cities. Assume the population variances are approximately the same and that the masses of turkeys sold in the stores are normally distributed.
