The deviation of a magnetic needle from the magnetic pole in a certain area in northern Canada is a normally distributed random variable with mean 0 and standard deviation 1.00. What is the probability that the absolute value of the deviation from the north pole at a given moment will be more than 2.4?
Answer to relevant QuestionsFor a normal random variable with mean 650 and standard deviation 40, find the probability that its value will be below 600. Let X be a normally distributed random variable with mean µ = 16 and standard deviation σ = 3. Find P(11 < X < 20). Also find P(17 < X < 19) and P(X > 15). Based on the research of Ibbotson Associates, a Chicago investment firm, and Prof. Jeremy Siegel of the Wharton School of the University of Pennsylvania, the average return on large-company stocks since 1920 has been 10.5% ...If X is a normally distributed random variable with mean -61 and standard deviation 22, find the value such that the probability that the random variable will be above it is 0.25. The daily price in dollars per metric ton of cocoa in 2007 was normally distributed with µ = $2,014 per metric ton and σ = $2.00. Find a price such that the probability that the actual price will be above it is 0.80.
