The following data is from a survey that was conducted in both 1996 and 2001. Did the rates of smoking differ from 1996 to 2001? *Smokers are defined as those who smoke every day. State the Null and Alternative hypothesis. If possible, USING EXCEL, run a CHI square test.

1996 2001
Grade Smokers* Non smokers Smokers* Non smokers
8th       1,101     13,566          815     13,852

We consider,

Null hypothesis: Smokers and Non smokers are same.

Alternative hypothesis: smokers and Non smokers are differs .

Here ,we get Chisquare test value which is 2.0215 which is greater than the benchmark 0.05 So,Here we accept the null Hypothesis...And there is no significant difference between smokers and non smokers..

Thanks.

If any doubts regarding this you can comment me..I will try my best to resolve your queries..
