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.

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.
