A sample of blood pressure measurements is taken for a group of​ adults, and those values​ (mm Hg) are listed below. The values

are matched so that 10 subjects each have a systolic and diastolic measurement. Find the coefficient of variation for each of the two​ samples; then compare the variation. Systolic 118 126 160 98 156 124 116 134 126 120 Diastolic 78 78 72 50 91 87 57 64 74 84

Answer:

Systolic variation coefficient (CVS) = 0.1446 = 14.46%

Diastolic variation coefficient (CVD) =  0.1789 = 17.89%

The variation, with respect to the mean, of the systolic pressure sample is slightly less than the variation of the Diastolic pressures.

Step-by-step explanation:

Systolic Mean (MS) = 127.8

Diastolic Mean (MD) = 73.5

Standard Deviation Systolic (sdS) = 18,486

Standard Deviation Diastolic (sdD) = 13.1508

The coefficient of variation is defined by:

Systolic variation coefficient (CVS) = sdS / MS = 18.486 / 127.8 = 0.1446 = 14.46%

Diastolic variation coefficient (CVD) = sdD / MD = 13.1508 / 73.5 = 0.1789 = 17.89%

Then, it can be concluded that the variation, with respect to the mean, of the systolic pressure sample is slightly less than the variation of the Diastolic pressures.

Answer:

i cant help with the first one but the others i think i can

- plastic (insulator) -stainless steel (conductor) -silver (conductor) -wood (insulator)

Also radiation could effect the system but changing the conductivity of some of the materials also change change the way the materials accept heat.  

Sorry about the first one :)
