Question

Find the numerical value of the area under the normal curve given the following information:between 1.23 and 2.01 standard deviations above the meanenter your answer as a decimal (NOT percentage) and lead with a zero...for example: 0.1234

Answer 1

In the z-table, find the values for z = 1.23, and z = 2.01.

We have the following

For z = 1.23, 0.89065

For z = 2.01, 0.97778

Find P(1.23 < z < 2.01)

[tex]\begin{gathered} P\left(1.23Rounding to four decimal place, the area between 1.23 and 2.01 standard deviation is 0.0871.
