(a) To determine To find: The mean of the distribution. Explanation Given: The probability density function is f ( x ) = 4 for x in [ 2.75 , 3 ] of the price of an item. Definition used: Uniform Distribution: If X is a random variable with probability density function f ( x ) = 1 b − a for x in [ a , b ] , then μ = 1 2 ( b + a ) (b) To determine To find: The standard deviation of the distribution. (c) To determine To find: The probability that the random variable is between the mean and 1 standard deviation above the mean.

Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could co…
