(a) Use a computer program to find the probability that a random variable having the normal distribution with the mean –1.786 and the standard deviation 1.0416 will assume a value between – 2.159 and 0.5670. (b) ...A random variable has a normal distribution with σ = 10. If the probability that the random variable will take on a value less than 82.5 is 0.8212, what is the probability that it will take on a value greater than 58.3? If the probability is 0.20 that a certain bank will refuse a loan application, use the normal approximation to determine (to three decimals) the probability that the bank will refuse at most 40 of 225 loan applications. If X is the total we roll with a pair of dice, for which the probability distribution is given on page 63, find the probability distribution of the remainder we get when the values of X are divided by 3. Consider the random variable X with the uniform density having α = 1 and β = 3. (a) Use the result of Example 7.2 to find the probability density of Y = | X|. (b) Find the probability density of Z = X4(=Y4).Post your question
