Question

which of the following functions will correctly find the area under the curve in p(z is between 1.57 and 1.84)? select the correct response: normalcdf (1.84,1.57) normalcdf (-1.84,-1.57) normalcdf (-1.57,1.84) normalcdf (-1.57,-1.84) normalcdf (1.57,-1.84) my answer is not listed among the given choices. normalcdf (1.57,1.84)

Explanation:

Step1: Recall normalcdf syntax

The normalcdf function takes arguments in the form $\text{normalcdf}(\text{lower bound}, \text{upper bound})$ to find the area under the standard normal curve between two z-scores.

Step2: Identify bounds for the interval

We need the area where $z$ is between 1.57 and 1.84, so the lower bound is 1.57 and the upper bound is 1.84.

Step3: Match to correct function

Substitute the bounds into the function format: $\text{normalcdf}(1.57, 1.84)$

Answer:

normalcdf (1.57, 1.84)
