Question

listed below are the measured radiation emissions (in w/kg) corresponding to cell phones a, b, c, d, e, f, g, h, i, j, and k respectively. the media often present reports about the dangers of cell - phone radiation as a cause of cancer. cell phone radiation must be 1.6 w/kg or less. find the a. mean, b. median, c. midrange, and d. mode for the data. also complete part e. 0.49 0.23 0.55 0.29 1.44 0.78 1.33 0.42 1.16 0.66 1.22
a. find the mean
the mean is 0.779
(type an integer or decimal rounded to three decimal places as needed.)
b. find the median
the median is 0.660
(type an integer or decimal rounded to three decimal places as needed.)
c. find the midrange
the midrange is
(type an integer or decimal rounded to three decimal places as needed.)

Explanation:

Step1: Arrange data in ascending order

0.23, 0.29, 0.42, 0.49, 0.55, 0.66, 0.78, 1.16, 1.22, 1.33, 1.44

Step2: Calculate mid - range formula

Mid - range = $\frac{\text{Minimum value}+\text{Maximum value}}{2}$

Step3: Identify minimum and maximum values

Minimum value = 0.23, Maximum value = 1.44

Step4: Calculate mid - range

Mid - range = $\frac{0.23 + 1.44}{2}=\frac{1.67}{2}=0.835$

Answer:

0.835
