deviation of the number with 20-20 vision in the class.
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
