What is the mean of the data set [3, 2, 2, 12, 6, 5, 14,4)?
O2
O 7

the mean is 6 but you don't have that as an option.

Explanation:

the mean is the average.

to find the mean you have to add all of your data first

3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48

then you have to divide your answer by how many numbers there are in total.

48 / 8 = 6

the mean is 6.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
