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
