I got 350.
Step-by-step explanation:
You will understand that two of the squares is 140. Well there are three sets of two squares in the contaminated section. Then there is one more square, which is only half of 140, which is 70.
140 x 3 = 420.
420 + 70 = 490.
490 - 140 (Two squares) = 350.
I hope this helps!

Ответ:
H0: p1=p2 versus Ha:p1≠p2
Step-by-step explanation:
Let p1 be the proportion experiencing the primary outcome with the treatment and p2 the proportion without the treatment.
We want to determine whether the proportion of persons having the treatment suffering the primary outcome of a fatal cardiovascular event is equal to the proportion of people without the treatment suffering the primary outcome of a fatal cardiovascular event.
The hypothesis is based on the study under observation. The claim is set as the alternate hypothesis.
The null and alternate hypotheses are
H0: p1=p2 versus Ha:p1≠p2
Both proportion ( with and without treatment ) are same
against the claim
Both proportion ( with and without treatment ) are not the same .
Option which gives the answer
H0: p1=p2 versus Ha:p1≠p2
is the best option.
