Question

A list of numbers has a mean of 8 and a standard deviation of 2.5. if x is a number in the list that is 2 standard deviations above the mean what is the value of x​

Answer 1

Answer:

This is a question that requires knowledge of standard deviation. Given that mean of the list is 8 and standard deviation is 2.5.

Now if x was one standard deviation above mean that would mean that x=8+2.5=10.5x=8+2.5=10.5.

However x is given to be two standard deviations above the mean so x=8+2.5+2.5=13x=8+2.5+2.5=13.
