Answer:
C)12
Step-by-step explanation:
-10 to 2 is 12 units away right?
Answer: a=2.3
Step-by-step explanation:
divide both sides by 2
4.6 divided by 2 is 2.3
The mean of the confidence interval is (0.3775 + 0.6225) / 2 = 0.5. Therefore, the standard deviation of the proportion would have been sqrt[0.5*(1 - 0.5) / n], where n is the sample size. This expression simplifies to sqrt(0.25/n).
A 95% CI has a corresponding z = 1.96, so since the distance from 0.5 to 0.3775 (or 0.6225 to 0.5) is equal to 0.1225. Therefore, if we divide 0.1225 / 1.96 = 0.0625, we get the value of the SD, and this should be equal to sqrt(0.25/n).
0.0625 = sqrt(0.25/n)
n = 64
This means that the proportion was 0.5 and the sample size was 64.
Convert the grams into milligrams. 0.5 = 500 (to covert you'll multiply .5 x 1000).
D/H x Q will be the formula to use now that we have like terms (mg).
D= dose to give
H = dose that is supplied
Q= quantity to give
In this case your numbers will be
D = 500mg
H = 250mg
Q = 1 tablet
500 ÷ 250 = 2
2 x 1 = 2
So, that means you will give 2 tablets to your patient.
