Question

please explain thought processs and reasoning

For the following questions, consider the picture below What fraction of the population has blood concentrations between 0.18 and 4.84 mmol/L? What percentage of the population has blood concentrations between 0.18 and 4.84 mmol/L? If the population consists of blood concentrations from each of the 7.53 billion humans on Earth, how many people have blood concentrations between 0.18 and 4.84 mmol/L? 0.8 0.6 0.4 0.2 0.0 4 4.84 7 2 0.181 Triglyceride concentration mmol/L

Answer 1

The area of the shaded region is approximately . (The total area under the curve is 1. Subtract out approximate areas of regions on both sides of the shaded region)

1-0.65 x 0.18-0.05 x 5 0.633

a) The fraction of population with blood concentration $\left ( C \right )$ between 0.18 and 4.184 is

P(0. 18 〈 C〈 4.84〉 0.633

b) The % of population with blood concentration $\left ( C \right )$ between 0.18 and 4.184 is

0.633 x 100% 63.3%

c) The number of people with blood concentration $\left ( C \right )$ between 0.18 and 4.184 is

0.633 x 7.53 billion 4.77 billion
