Question

use the accompanying radiation levels (in \\( \frac { w } { k g } \\) ) for 50 different cell phones. find the percentile corresponding to \\( 1.43 \frac { w } { k g } \\)
click the icon to view the radiation levels.
the percentile corresponding to \\( 1.43 \frac { w } { k g } \\) is
(round to the nearest whole number as needed.)

Explanation:

Step1: Count the number of values less than or equal to \(1.43\)

Count the number of data points in the table that are less than or equal to \(1.43\). There are \(39\) such values.

Step2: Calculate the percentile

Use the formula \(P=\frac{\text{Number of values}\leq x}{\text{Total number of values}}\times100\). Here, \(x = 1.43\), the number of values \(\leq1.43\) is \(39\), and the total number of values \(n = 50\).

$$P=\frac{39}{50}\times100=78$$

Answer:

\(78\)
