Using the binomial distribution, it is found that the mean of X is of 12, with a standard deviation of 3.36.
For each chip, there are only two possible outcomes, either it is defective, or it is not. The probability of a chip being defective is independent of any other chip, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
Probability of exactly <u>x successes on n repeated trials, with p probability.</u>
The mean of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem:
- Six percent of computer chips produced by Cheapo Chips are defective, hence
.
- Each month a random sample of 200 chips manufactured that month are taken, hence

Then:


The mean of X is of 12, with a standard deviation of 3.36.

Answer:
8
Step-by-step explanation:
Given
(m + n)³ ← substitute m = 1, n = 1 into the expression
= (1 + 1)³ = 2³ = 2 × 2 × 2 = 8
Answer:
he has 300 nickels
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
To be divisible by 4 the last two digits have to be divisible by 4
so
is 63 divisibly by 4?
no
because is odd and four is even
so we can conclude that 563 is not divisible by 4
