A random variable X follows a uniform distribution with the following parameters: Minimum value A is 2 and maximum B value is 4.
What is the standard deviation of this random variable?
To raise workplace morale, a company decides to have a contest. They get a medium-sized, unusually shaped glass container and fill it with water; the contest is to guess the number of ounces of water in the container. The winner will receive an assortment of wines and cheeses. The distribution of errors (i.e., how far away each person's guess is from the correct answer) follows a standard normal distribution (i.e., a normal distribution with mean 0 and variance 1).
What is the probability that a randomly chosen person's guess is more than 2 ounces away from the correct answer?
The random variable Z follows a standard normal distribution; that is, it is normal with mean 0 and standard deviation 1.
Find P(Z< 1) .
