A factory produces components of which 1% are defective. The components are packed in boxes of 10. A box is selected by random.
a) Find the probability that there are at most 2 defective components in the box.
b) Use a suitable approximation to find the probability of having at most 3 defective (inclusive 3 cases) components out of 250.

Expert Solution
Answer:
Given that,
A factory produces components of which 1% are defective.
The components are packed in boxes of 10.
A box is selected by random.
i.e,
n=10
p=0.01
q=1-p
=1-0.01
q=0.99
Where,
(a).
Find the probability that there are at most 2 defective components in the box:
:
=0.9044+0.0914+0.0019
=0.9977
(b).
Use a suitable approximation to find the probability of having at most 3 defectives (inclusive 3 cases) components out of 250:
i.e,
n=250, p=0.01 and q=0.99
:
=0.0811+0.2048+0.2574+0.0215
=0.5648

Fries weighing 480g and a standard deviation of 20g are packed
in a factory. A complaint suggests that the bags of these fries
weigh less than 480g, so we took a sample of 100 bags that turned
out to have an average of 477g. Test the null hypothesis H0> =
480 against the alternating HA <480 with a significance level α
= 0.1. Calculate Zc and Z. It fails to reject the null
hypothesis?

Suppose that an electric car contains six similar components two
of which are defective. Three of these components are selected at
random, removed from the car, and inspected. Let Y equal the number
of defectives observed, where Y = 0, 1 ,or 2. Determine the pmf of
Y and graph its CD
