The contingency table shows a random sample of people in a country divided up by region and whether
they would wear a mask during a virus pandemic. At a 10% Level of Significance, test to determine whether
willingness to wear a mask depends on the region in which people live.
1. The hypotheses are :
ne
O Ho:Region and willingness to wear a mask are independent
Ha:Region and willingness to wear a mask are dependent
O Ho:Region and willingness to wear a mask are dependent
Ha:Region and willingness to wear a mask are independent

2. This is a O rightO leftO two tailed test; d.f. =
3a. The STS (to 2 decimals) is x

3b. The P-value (to 3 decimals) =
4a. The decision at a = 10% is
O Do not reject Ho
