Ok first of all, I EXTREMELY appreciate your use of parenthesis. Ok so first just raise both sides to the power of 1/2.
You'll see why I didn't include a negative. Then apply the log base 3/8 and you get
Then you split the log up and you get
You couldn't put a negative value for a log. That is why I excluded the negative part of the sqrt.

Answer: a. Mean = 0.696364
b. Median = 0.64
c. Midrange = 0.895
d. There is no Mode
e. 2. The maximun data value is the most relevant statistic, because it is closest to the limit of 1.6W/kg and that cell should be avoided.
Step-by-step explanation:
a) Mean is an average number of the data set, calculated by the sum of all the value divided by the quantity of the set:
mean =
mean = 0.696364
b) Median is the middle number in the list of numbers. In this case, since there are 11 elements in the set, the middle number is:
sorted numbers of the data set:
0.22 0.24 0.29 0.35 0.54 0.64 0.75 0.81 1.02 1.23 1.57
median = 0.64
c) Midrange is another type of average number. It is calculated as:
midrange =
midrange =
midrange = 0.895
d) Mode is the number that appears most often in the list of numbers. For this data set, each number appears only one time, so there is no mode.
Mode = 0
e) According to the question, cell phone radiation is dangerous when it is higher than 1.6W/kg. The cell phone with the maximum data value (1.57 W/kg) should be avoided, since it is too close to the limit described.
So, the measures of center are not the most important statistic to be observed but the maximum data value.
