(1 point) Two points are selected randomly on a line of length 10 so as to be on opposite sides of the midpoint of the line. In other words, the two points X and Y are independent random variables such that X is uniformly distributed over [0,5) and Y is uniformly distributed over (5, 10]. Find the probability that the distance between the two points is greater than 2. answer:

(1 point) Two points are selected randomly on a line of length 16 so as to be on opposite sides of the midpoint of the line. In other words, the two points X and Y are independent random variables such that X is uniformly distriuted over [0,8) and Y is uniformly distributed over (8,16] Find the probability that the distance between the two points is greater than 6. P(|X – Y| > 6) =

(3 pts) The lengths of the sardines received by a certain cannery are normally distributed with mean 4.62 inches and a standard deviation 0.23 inch. What percentage of all these sardines is between 4.35 and 4.85 inches long? (3 pts) Suppose that the weight (X) in pounds, of a 40-year-old man is a normal random variable with standard deviation σ = 20 pounds. If 5% of this population is heavier than 214 pounds what is the mean μ of this...

Can Someone help with problems 4 and 5?
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...

1) Rate data often follow a lognormal distribution. Average power usage (dB per hour) for a particular company is studied and is known to have a lognormal distribution with parameters μ = 4 and σ = 2. What is the probability that the company uses more than 270 dB during any particular hour? 2) A certain type of device has an advertised failure rate of 0.01 per hour. The failure rate is constant and the exponential distribution applies. (a) What...

D Question 5 10 pts A geologist is attempting to measure the distance between two mountain peaks by taking the average of a series of measurements. Each measurement X, is an ii.d. random variable with mean d and variance of 10 inches. Using Chebyshev's inequality, how many measurements must the geologist make in order to be 99% certain that the value he obtains is within 1/4 inch of the actual distance?
