I just need help with this question.

For a sample of size 5, x1 - mean = -5, x2 - mean = 9, x3 - mean = -7, x4 - mean = -2 and x5 - mean = 5

What is standard deviation... answer is 6.782 by squaring all the answers, dividing by n-1 and finding square root.

However, what is the mean of the sample.Is this possible to get missing both x1, x2, x3, x4, x5 and also missing the mean?
