4. An auto manufacturer determines their engines test an average of 120,000 miles with a standard deviation of 15,000 miles. They decide to offer a warranty on the engine for the first 100,000 of its life. What is the probability an engine from one of their cars will need work done under this warranty? 5. The weights of a species of fish are normally distributed with a mean of 4.2 pounds with a standard deviation of 0.8 pounds. What is the probability one of these fish caught at random weighs between 3 and 5 pounds? & Which value la derest to the standard deviation of the continuous randem variable with the following normal distribution? 26 d. 12 4.
