Question 1198760: 1- The probability of an integrated circuit failing a quality test performed by the quality
section in the factory is 0.0045 In a batch of 25 integrated circuits (assuming a binomial
distribution) calculate the probabilities that:
a) 10 will pass
b) 15 will fail
c) at least 20 will pass
d) Fewer than 3 will fail.
2- Fuses blowing current follow a normal distribution with a mean current of 2 amp and a
standard deviation of 0.12 amp. Calculate by using normal distribution the proportion of
fuses blowing with:
a) Currents between 1.75 amp and 2.13 amp.
b) Current less than 2.82 amp
c) Current greater than 1.24

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In this my response, I will solve part 2, ONLY.

(a)  P = normalcdf (1.75, 2.13, 2, 0.12).     Use your calculator.


(b)  P = normalcdf (-9999, 2.82, 2, 0.12).    Use your calculator.


(c)  P = normalcdf (1.24, 9999, 2.82, 0.12).  Use your calculator.

Next time, please do not pack more than one problem per post.
