A machine fills bags of candy. Due to slight irregularities in the operation of the machine, not every bag gets exactly the same number of pieces. Assume that thenumber of pieces per bag has a mean of 133 with a standard deviation of 2. Use the 68-95-99.7 rule to find the percentage of values in the distribution between 133and 137. Complete parts a. and b. below.a. What is the percentage of values in the distribution between 133 and 137?% (Round to one decimal place as needed.)
