Suppose an agricultural scientist plants two different types of corn seed to test the claim that they produce the same average yield. The seeds are planted on eight randomly selected plots of land, each of which has one half of the plot planted with Type 1 seed and the other half planted with Type 2 seed. Calculate a 95% confidence interval estimate for the mean difference between the yield for Type 1 seed (Population 1) and Type 2 seed (Population 2). Round each of your answers to one decimal place; add a trailing zero as needed.

Data Set:

Type 1:

1981, 2000, 1985, 2467, 2110, 2034, 2220, 1426

Type 2:

2011, 1966, 2001, 2468, 2124, 1989, 2195, 1451
