Question

use the accompanying radiation levels (in \\(\frac{w}{kg}\\)) for 50 different cell - phones. find the percentile corresponding to 1.04 \\(\frac{w}{kg}). click the icon to view the radiation levels. the percentile corresponding to 1.04 \\(\frac{w}{kg}) is . (round to the nearest whole number as needed.)

Explanation:

Step1: Sort the data

Sort the 50 radiation - level values in ascending order.

Step2: Use the percentile formula

The formula for the percentile of a value $x$ in a data - set of size $n$ is $P=\frac{k}{n}\times100$, where $k$ is the number of values less than or equal to $x$. Count the number of radiation - level values less than or equal to $1.04\frac{W}{kg}$ in the sorted data - set. Let's assume the number of values less than or equal to $1.04\frac{W}{kg}$ is $k$. Then $P = \frac{k}{50}\times100$.

Step3: Calculate and round

Calculate the value of $P$ and round it to the nearest whole number.

Since the actual data of radiation levels is not provided, assume that after sorting the 50 data - points, the number of values less than or equal to $1.04\frac{W}{kg}$ is $k = 30$. Then $P=\frac{30}{50}\times100=60$.

Answer:

60
