Consider the following hypothesis test for the mean difference. (Give your answers correct to four decimal places.)
(a) Determine the p-value for Ho:
μd = 0 and Ha:
μd > 0, with n = 20 and t
= 1.98.
(b) Determine the p-value for Ho:
μd = 0 and Ha:
μd ≠ 0, with n = 18 and t =
-1.88.
(c) Determine the p-value for Ho:
μd = 0 and Ha:
μd < 0, with n = 30 and t
= -2.67.
(d) Determine the p-value for Ho:
μd = 0.75 and Ha:
μd > 0.75, with n = 11 and
t = 3.43.
Also, when i try to do this on my calculator i get error. How can i fix my calculator so i can do this?

A local greenhouse sells coffee-tree saplings. They price their
saplings based on the height of the plant. They have two workers,
Susan and Karen, who measure the saplings for pricing. The
greenhouse manager wants to determine if there is a significant
difference in the measurements made by these two individuals. She
has them measure the same set of 15 saplings. Assume that the
differences are calculated as Susan – Karen.
