Math Problem Statement
Find the area of the indicated region under the standard normal curve. -1.6-0.6
Solution
To find the area under the standard normal curve between and , we need to use the cumulative distribution function (CDF) of the standard normal distribution, which provides the area to the left of any given -value.
Steps:
- Find the area to the left of using the standard normal table (or a calculator with the normal distribution function):
- Find the area to the left of :
- Calculate the area between and by subtracting the two areas:
Thus, the area under the standard normal curve between and is approximately 0.2195.
