click the icon to view the table.
the percentage of data items in a normal distribution that lie between ( z = - 2.1 ) and ( z = - 0.1 ) is (square%).
(type an integer or a decimal)

Explanation:

Step1: Find the area corresponding to \(z = - 2.1\)

Using the standard normal distribution table, the area to the left of \(z=-2.1\) is \(0.0179\).

Step2: Find the area corresponding to \(z=-0.1\)

Using the standard normal distribution table, the area to the left of \(z = - 0.1\) is \(0.4602\).

Step3: Calculate the area between \(z=-2.1\) and \(z=-0.1\)

Subtract the smaller area from the larger area. \(A=0.4602 - 0.0179=0.4423\)

Answer:

\(44.23\)
