Answer:
8 and 2.529
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
Given that
Total number of questions is n = 40
The Probability of correct answer is p = 
So, the probability of the wrong answer is q =
= 
Moreover, this is the binomial distribution
Based on the above information
The mean is


= 8
Now the variance is

= 
So, the standard deviation is

= 2.529
hence, the mean and the standard deviation is 8 and 2.529 respectively
