A researcher wishes to test claim that there is no difference in the life span of two types of reptiles: the Nile crocodile and giant sea turtle. Sample data including the average lifespan of both reptiles are provided below. Test the claim using α=0.05.

Nile Crocodile Giant Sea Turtle

X ¯ 1 = 45

s 1 ==2.6

n 1 =12

X ¯ 2 =44

s 2 =6.5

n 2 =10

State the claim:

H 0 μ 1   claim

H 1 μ 1≠ μ 2

Determine the direction of the tails: Left, Right, or Two:

Find the critical value: +/-

Compute Test Point (round to 2 place values) :

Do we Reject or Do Not Reject?  

Summarize: There is not enough evidence to  the claim.
