Answer:
The standard deviation of the number of people that test positive for the HIV virus =
σ =1.427
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given the probability that test positive for the HIV virus 'p' = 3% =0.03
Given random samples 'n' = 70
by using binomial distribution
<em>The mean of the samples test positive for the HIV virus </em>
<em> μ = n p = 70 X 0.03 = 2.1</em>
<em>The standard deviation of the number of people that test positive for the HIV virus</em>
<em> σ = </em><em></em>
σ = √70 ×0.03×0.97 =√2.037 = 1.427
<u><em>Conclusion</em></u>:-
The standard deviation of the number of people that test positive for the HIV virus = σ =1.427
Answer:
The plot is attached.
Step-by-step explanation:
Plot the function y(x)=e^–0.5x sin(2x) for 100 values of x between 0 and 10. Use a 2- point-wide solid blue line for this function.
The step value for x is (10-0)/100=0.1.
Plot the function y(x)=e–0.5x cos(2x) on the same axes. Use a 3-point-wide dashed red line for this function.
The step value for x is the same as the previous function.
