Question

7. Find the mean and standard deviation for the set
of values 13, 15, 17, 18, 21, 12, 10.

Answer 1

Explanation:

I've got no idea of what standard deviation is, never heard

Bur I can find you the mean though

13+15+17+18+21+12+10=106

106÷7(dividing by how many numbers are there)=15.14
