Answer: Mean = 2.91 and Variance = 0.087
Step-by-step explanation:
Given : The probability of a correct classification of any part p= 0.97.
The number of parts are inspected : n=3
Let the random variable X denote the number of parts that are correctly classified.
For binomial experiment , the mean and variance is given by :-
Then, the the mean and variance of X will be :-
![\mu=3(0.97)=2.91\\\\\sigma^2=np(1-p)=3(0.97)(0.03)=0.0873\approx0.087\ \ [ \text{Rounded to three decimal places}]](https://tex.z-dn.net/?f=%5Cmu%3D3%280.97%29%3D2.91%5C%5C%5C%5C%5Csigma%5E2%3Dnp%281-p%29%3D3%280.97%29%280.03%29%3D0.0873%5Capprox0.087%5C%20%5C%20%5B%20%5Ctext%7BRounded%20to%20three%20decimal%20places%7D%5D)

Answer:
The estimated sum is ≈10
Step-by-step explanation:
This depends on how your professor wants you to estimate sums. Logically, though, a value of nearly 4 and a value of just over 6 add to about 10. The exact answer would be a bit over 10, at ≈10.14117
