The manager of a local soft drink bottling company believes that when a new beverage-dispensing machine is set to dispense 7 ounces, it in fact dispenses an amount x at random anywhere between 6.5 and 7.5 ounces inclusive. Suppose x has a uniform probability distribution.
a. is the amount dispensed by the machine a discrete or a continuous random variable?
b. Find the mean and standard deviation for the distribution.
c. what is the probability that for a randomly selected bottle the machine will dispense at 6.75 ounces?
d. what is the probability that for a randomly selected bottle the machine will dispense more than 7.25 ounces?
e. what is the probability that for a randomly selected bottle the amount the machine dispenses is within one standard deviation of he mean?
