Mean, μ: 3.6
Variance, σ2: 11.44
Steps
(10 - 3.6)2 + ... + (2 - 3.6)2
5
=
57.2

= 11.44
σ = √11.44
= 3.38
The answer should be 42.
Since there are 60 questions in the test and she managed to answer 70% of the questions correctly, that means that she answered 70% out of 60 questions correctly.
So you need to calculate how much 70% out of 60 is. Since % is always measured on a base from 0 (%) to 100(%), then 70% is equal to the fraction 70/100, simplified to 7/10. To know how much 7/10 out of 60 is,you just multiplie them and your answer will be 42.
I hope this helps you forward.
