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
the mean is 0.779 (type an integer or decimal rounded to three decimal places as needed.)
b. find the median.
the median is 0.680 (type an integer or decimal rounded to three decimal places as needed.)
c. find the midrange.
the midrange is 0.835 (type an integer or decimal rounded to three decimal places as needed.)
d. find the mode.
select the correct choice below and, if necessary, fill in the answer box within your choice.
a. the mode(s) is (are)
(type an integer or a decimal. do not round. use a comma to separate answers as needed.)
b. there is no mode

Explanation:

Step1: Organize data

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

Step2: Calculate median

There are 11 data - points. The median is the 6th value when data is ordered. So the median is 0.660.

Step3: Calculate mid - range

The mid - range is calculated as $\frac{\text{minimum value}+\text{maximum value}}{2}$. The minimum value is 0.23 and the maximum value is 1.44. So the mid - range is $\frac{0.23 + 1.44}{2}=0.835$.

Step4: Find mode

No value repeats more frequently than others, so there is no mode.

Answer:

b. 0.660
c. 0.835
d. B. There is no mode
