Answer:
$50 for Brian
$90 for Tim
$100 for Kenny
Step-by-step explanation:
Let 5x = amt for Brian
9x = amt for tim
10x = amt for ken
5x + 9x + 10x = 240
24x = 240
x = 10
5x = 5(10) = $50 for Brian
9x = 9(10) = $90 for Tim
10x = 10(10) = $100 for Kenny

Because the P-value of 0.19 small(such as 0.05 or lower), accept the null hypothesis of independence between the treatment and whether the subject stops smoking. This suggests that the choice of treatment is insignificant.
P-value>0.05 , we accept the null hypothesis. When the P-value is greater than 0.05 , the test is insignificant.
This means that the choice of treatment is insignificant.
