The data below are for two different types of straw seed that were used on adjacent plots of land. The listed values are the yields of straw in cwt (100 lb, or hundredweight) per acre, and the yields are paired by the plot of land that they share. Complete parts (a) through (c).
Type 1 Type 219.25 2523 23.7522.75 24.2522.75 28.2522.25 22.7519.5 19.7524.5 22.2515.5 1618 17.2514 1617 17.25
Using a 0.05 significance level, test the claim that there is no difference between the yields from the two types of seed. Let mu Subscript dμdbe the mean of the population of differences of type 1 minus type 2 and write the hypotheses.
The null hypothesis is
