Answer:
a) 752 medical files should be included.
b) 372 medical files should be included.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
The margin of error is of:
90% confidence level
So , z is the value of Z that has a p-value of , so .
Question a:
This is n for which M = 0.03. We have no estimate, so we use . So
Rounding up:
752 medical files should be included.
Question b:
Now we have that:
So
Rounding up:
372 medical files should be included.
One way to find the answer is to take Point O and Point Q and add them, setting it to equal 180 so:
(x+17)+(6x-5)=180
Combine like terms:
7x+12=180
Subtract 12 from 180:
7x=168
Then divide 7 to isolate the x:
So then x=24 and you want the measure of ROP so take 24 and add it to 17:
Final answer ROP=41
Answer:
a number subtracted from five
Step-by-step explanation:
All the other choices mean n - 5, except this one, which means 5 - n.
The answer would be, 1.75 because 3/4 of 1 is 75% pulse you spreading have a whole, so 1.75.
