NR 599 WEEK 7 ASSIGNMENT LAB

A. Description of the decision or problem

Treatment of pulmonary arterial hypertension with the

medication Selexipeg, an oral medication used to lower the blood

pressure in the lungs through dilation of the of the vessels that

supply the lungs (Drugs, 2018). Is this medication an effective

treatment for PAH or not?




B. How the interval would impact the decision and what level of

confidence would be most appropriate and why?

The interval could be impacted by the sample size used,

percentage, and population size.

The sample size affects the interval by indicating that the larger

the sample size the more accurate and the smaller the confidence

interval will be. Percentage affects the intervals because if say

90% have effect treatment and 10% don’t then it’s more likely

that the medication will work for most and it’s going to be the

more accurate and reflect true for the population. Population

size will make a difference if use a small group, if a much larger

group is used then the population size will not be a factor.
