Question

use the accompanying table of z - scores and percentiles to find the percentage of data items in a normal distribution that lie a. below and b. above a z - score of 1.7
click the icon to view the table of z - scores and percentiles.
a. the percentage of data items that lie below the z score is %
(round to two decimal places as needed.)

Explanation:

Step1: Locate the z - score in the table

In the standard table of z - scores and percentiles, when \(z = 1.7\).

Step2: Read the corresponding percentile

The percentile corresponding to \(z=1.7\) is \(95.54\%\) (from the standard normal distribution table where for \(z = 1.70\), the cumulative probability \(P(Z<1.70)\) is found by looking up the row for \(1.7\) and the column for \(0.00\) in the standard normal table).

Answer:

\(95.54\)
