The city council is considering a law that would ban smoking
The city council is considering a law that would ban smoking in all public facilities. A sample has been selected from the community and tested for support of the ordinance. Is there a statistically significant relationship between age and support for the anti-smoking law? Use the five step model as a guide and write a sentence or two interpreting your results.
| Less than 40 | More than 40 | |||
| SUPPORT | For | 145 | 78 | 223 |
| Against | 103 | 169 | 272 | |
| Total | 248 | 247 | 495 |
Solution
less then 40
total are 248
for = 145 which will be 58.46%
against = 103 which will be 41.54%
which means majority population is in support for this in this group.
more than 40
total 247
for = 78 = 31.5%
against = 169 = 68.5%
so majority are against in this group.
if we consider whole at one time.
total = 495
for = 223 = 45%
against = 272 = 55%
so on the whole majority is against the law.
