Question

Problem 4. A circular-shaped archery target has three concentric circles painted on it. The in- nermost circle has a radius of 1/V3 feet, the middle has a radius of 1 foot, and the outermost circle has a radius of v3 feet. An arrow hitting in the innermost circle counts for 4 points, between the in nermost and middle circle 3 points, between the middle and outermost circle 2 points, and not hitting within the outermost circle 0 points. Suppose that the distance R in feet from the exact center of the target that any arrow shot by a certain archer hits the target follows the distribution Find numerical values for B,S and Varls Problem 5. Suppose that the continuous random variable X has the distribution fx(r), -00< z < oc, which is symmetric about the value z-0. Evaluate the integral: Fx(t)dt where Fx(t) is the CDF for X, and k is a non-negative real number. Hint: Use integration by parts.

Can Someone help with problems 4 and 5?

Answer 1

Do check the calculations of ques 4,but the process is perfect.
