Google tells you the average cat’s weight is 45 lb. You want to test it.
1 What is hypotheses? (in math terms and words)
2 Let alpha level to be 0.01. Conduct a hypothesis test (H0, p value, conclusion).
|
A (cat numbers) |
300 |
|
B (average weight) |
38 |
|
C (sample standard deviation) |
7 |
3 If someone tests if average weight > 45 lb. What is the hypotheses and conclusions (on same data)?

Bull A’s EPD for yearling weight is +45 lb. Bull B’s EPD for
yearing weight is -5 lb.
a.
What is the expected difference in average yearling weights of
progeny of these two bulls?
b.
Will some of Bull B’s progeny have heavier yearling weights than
some of A’s progeny? Why?

It is suggested that the true average weight of college
football players is 200 lb. In a sample of 30 players, the sample
average is 206.73 lb. The sample standard deviation is 6.35 lb.
Does the true average weight differ from what was suggested? Test
the appropriate hypotheses about the true average weight of college
football players. Use α=0.05.
