Question

You are conducting a test of independence to see if getting the flu is independent of whether or not you got a flu shot.

Here is the sample data.

Category	Got the Flu	Did not get the Flu
Got Flu Shot	30	40
Did not get Flu Shot	33	38

1) The expected observations for this table would be

Category	Got the Flu	Did not get the Flu
Got Flu Shot
Did not get Flu Shot

The resulting (O-E)^2/E for finding the test are:

Category	Got the Flu	Did not get the Flu
Got Flu Shot
Did not get Flu Shot

2) What is the chi-square test-statistic for this data? (add the results from the previous table)
x^2=

What is the P-Value for this test-statistic?
P-Value =

3) Can you conlude (at the 0.05 significance level) that getting the flu is independent of whether or not you got the flu shot?

Yes independent: getting the flu is independent of if you got the flu shot.
No not independent: getting the flu is dependent on if you got the flu shot.
