The area beneath the normal density curve is separated into three regions by the values a and b. Set the mean of the normal density curve to 6.4, the standard deviation to 0.7, and the x-value of b to 6.8. First, determine the value of the area to the right of b.


Extracted text: Area right of b= Place a so that it equally divides the area to the left of b. What is the x-value of a? x-value of a =
