A machine is set to pump cleanser into a process at a rate of 6 gallons per minutes. Upon inspection, it is learned that the machine actually pumps cleanser at a rate described by the uniform distribution over the interval 5.5 to 8.5 gallons per minute. Find the probability that between 6 and 7 gallons are pumped during a randomly selected minute.

4. A yogurt cup is advertised as containing 6 oz of yogurt but the machine that fills the cups doesn't put exactly 6 oz of yogurt into each cup. The amount varies slightly. The amount of yogurt follows a normal distribution with a mean that can be set to any desired amount by adjusting the machine. The standard deviation of the amount of the yogurt is always 0.05 oz, regardless of the mean amount. If the company wants to be...
