Some students decided to test the assertion that one cannot tell the difference between butter and a particular brand of margarine. They recorded their results as follows
Could Tell Could not tell
Male 16 14
Female 21 9
To test if there is any significance between the ability of males and females in distinguishing between butter and margarine, the test statistic is equal to
1) 0.13
2) 1.76
3) 1.83
4) 0.17
5) 0.42
Thanks for your help!
