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 | ||
10th | 2,107 | 12,560 | 1,833 | 12,834 | ||
12th | 3,187 | 11,479 | 2,932 | 11,734 |
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.
