You are conducting a test of independence to see if getting the flu is independent of whether or not you got a flu shot. Use = 0.05. Report all answers accurate to four decimal places.
Here is the sample data.
Category | Got the Flu | Did not get the Flu |
Got Flu Shot | 47 | 39 |
Did not get Flu Shot | 32 | 14 |
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 for finding the test are:
Category | Got the Flu | Did not get the Flu |
Got Flu Shot | ||
Did not get Flu Shot |
What is the chi-square test-statistic for this data? (add the results from the previous table)
What is the p-value for this test-statistic?
P-Value =
Can you conlude (at the 0.05 significance level) that getting the flu is independent of whether or not you got the flu shot?
