Given that 33.6% of all possible observations of the very bar less than 10 determine the area under the density curve that lies to the right of 10.

Find the area above 29 for a N(15,5) distribution

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 4.00, the standard deviation to 0.33, the z-value of a to -3.03 and the z-value of b to be 3.03. determine the area to the left of a, the area between a and b, and the area to the right of b.

What z value has an area to the right of 0.0418?
