Standard deviation
** **
below, enter the following numbers, one to a line, in the given order:
The number which is two standard deviations less than the mean.
The number which is one standard deviation less than the mean.
The number which is equal to the mean.
The number which is one standard deviation more than the mean.
The number which is two standard deviations more than the mean.
Starting in the next line give a brief explanation of what your numbers mean and how you obtained them

I am not understanding which number would be two standard deviation less than the mean or one standard deviation..
When it comes to two standard deviations less than the mean does that mean to double the standard deviation.. which is 0.0205 and then subtract that from the mean? which is .1791.. which then gives 0.1586 after subtracted. So whatever number is closest to .1586 would be the number that is two standard deviations less than the mean?

What does it mean two standard deviations less than the mean?
@&
Two standard deviations means two times the standard deviation.
Two standard deviations less than the mean would be the mean, minus two standard deviations.
In other words, assuming .0205 is two times the standard deviation (you haven't actually stated what the standard deviation is so I can't be sure), you have interpreted it correctly.
