The contingency table shows a random sample of people divided up by gender and hair color. At a 1% Level
of Significance, test to determine whether gender and hair color are independent.
1. The hypotheses are :
O Ho:Gender and hair color are not independent
Ha:Gender and hair color are independent
O Ho:Gender and hair color are independent
Ha:Gender and hair color are not independent
2. This is a O rightO twoOleft tailed test; d.f. =
or
%3D
3a. The STS (to 2 decimals) is x =
3b. The P-value (to 3 decimals) =
4a. The decision at a = 1% is
O Do not reject Ho
O Reject Ho
