The probability that a person has 20-20 vision is
0.13 The class is 40 students. What is the mean and the Standard deviation of the number with 20-20 vision in the class.

Expert Solution

Answer:-

Given that:-

The probability that a person has 20-20 vision is
0.13 The class is 40 students.

What is the mean and the Standard deviation of the number with 20-20 vision in the class.?

The probability that a person has 20-20

Required information is given by ,

p= 0.13

and n= 40

Calculate :

What is the mean and the Standard deviation of the number with 20-20 vision:

We have to obtain Mean and standard deviation of the number with 20-20 vision is,

Here,

Mean is

Standard deviation is

Therefore,

Mean

Standard deviation
