(Show all work for credit, including calculations and complete parts a) Find all variables( SE, z or t, P-value, p hat, etc)

Grubs 47 54 64 76 88 97
Cinch 55 60 62 91 76 109

Does the difference in samples give us enough evidence to conclude that there is a difference between grub infestation and cinch infestation? Perform a hypothesis test, and state your conclusion.
