Answer:
19
Step-by-step explanation:
This was done the normal way of multiplying and dividing first:
If p=1 and q=4, evaluate the following expression:
4q − p/p + q = ?
4(4) - 1/1 + 4 = 16 - 1 + 4 = 19
If you wanted to do the addition and subtraction first, the equation would have been:
(4q - p)/(p + q) = ?
(4(4) - 1)/(1 + 4) = 15/5 = 3
With the parentheses, the order of operations is done in the parentheses first.
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.
