Question

Total plasma volume is importan in derminine the required plasma component in blood replacment therapy for a person undergong surgery, plasma volue is influeced by the overhealth and physical activity of an indviaul suppose that a ramdom sample of 45 male firefighters are tested and that they have a plasma volume sample mean of xtop - = 37.5 ml/kg assume that o=7.50 ml /kg for the ditribution of blood plasma a) find a 99% confidence interval for the population mean blood plasma volume in male firefighters. what is the margin of error b) what conditions are necessary for your calculations,

Explanation / Answer

n=45

Mu = 37.5

SD = 0.75

a)

z for 99 % confidence = 2.576

Margin of Error = z*SD/sqrt(n)

= (2.576 * 7.5) / sqrt(45)

= 2.88 Answer

Confidence Interval :

(37.5 - 2.88 , 37.5 + 2.88)

=( 34.62 , 40.38 ) Answer

b)

Necessary Condition :
