6. The average number of acres used for growing tobacco in Kentucky is 75,300 acres per year, with a

standard deviation of 5,000 acres.

What is the probability that less than 85,300 acres and more than

70,300 acres will be used for growing tobacco?

Don't understand how they got 68.3%

Im assuming the distribution is normal and my final answer is .8185 or 81.8%

Am I missing something?
