In 1908, William Gosset published the article €œThe Probable Error of a Mean€ under the pseudonym of €œStudent€ (Biometrika, Vol. 6, No. 1). He included the data listed below for yields from two different types of seed (regular and kiln dried) that were used on adjacent plots of land. The listed values are the yields of straw in cwt per acre, where cwt represents 100 lb. Use a 0.05 significance level to test for a correlation between yields from regular seed and kiln-dried seed. Are the results useful for addressing the main purpose of the experiment?
