There is enough evidence to conclude that taking aspirin cannot reduces the chance of cancer.
Given sample size of patients take aspirin 11037, sample size of patients who have assigned placebo group be 11034. 104 doctors who take aspirin had a heart attack, 189 doctors had placebo had heart attacks.
First we have to form hypothesis.


We have to find the respective probabilities.
=104/11037
=0.0094
=189/11034
=0.0171
Now their respective margin of errors.
=
=0.0009
=
=0.0011
Hence the distribution of the differences,they are given by:
p=
=0.0094-0.0171
=-0.0077
S=
=
=0.00305
z=(p -f)/S (In which f=0 is the value tested at the null hypothesis)
=(-0.0077-0)/0.00305
=-2.52
p value will be 0.005.
p value of 0.05 significance level.
z=1.96.
1.96>0.005
So we will reject the null hypothesis which means it cannot reduce the whole chance of becomming a heart attack.
Hence there is enough evidence to conclude that taking aspirin cannot reduces the chance of cancer.

Answer:
Buddie
Buddie should enter on line 6 of the income section:
capital gains or losses that he incurred for the past year.
Step-by-step explanation:
Line 6 asks about the capital gains or losses from the past year so that the AGI total could be obtained before deductions are made. Where Line 6 is filled, there are some other forms that will accompany it, like Schedule D and 1099-B or 1099-S forms, which record the capital gains or losses. All capital gains that are not excludable must be stated for income tax purpose.
