Question: (10 points total)

Yellowstone National Park has really big teddy bears, some more "bear" than "teddy". Suppose a random sample of n=54 bears yields a mean weight of \[\bar{X}\] = 282.9 lbs. Suppose further that the population standard deviation is known and is σ = 121.8 lbs. Construct an

α = 0.10 critical region test (two sided) of the claim that the population mean weight is

μ = 250 lbs.

Include in your answer the following:

7a (2 points) The null and alternative hypothesis

7b ( 5 points) The critical region

7c (3 points) The final conclusion.
