Answer:
D. The z- score of the bags is equal to a value of 0.
Step-by-step explanation:
The probability that a normally distributed data with statndard deviation σ and a mean, μ,exceeds a value x, is given by
P(X > x)=1-p(X < x)= 1- P(z< ![\frac {x- μ} \frac{{σ}{sqrt η}}](https://tex.z-dn.net/?f=%5Cfrac%20%7Bx-%20%CE%BC%7D%20%5Cfrac%7B%7B%CF%83%7D%7Bsqrt%20%CE%B7%7D%7D%20)
Now,
Given:
weight of corn chips dispensed into a 14-ounce bag by the dispensing machine is a normal distribution with
mean = 14.5 ounces
standard deviation =0.2 ounce.
So,
If 100 bags of chips are randomly selected the probability that the mean weight of these 100 bags exceeds 14.6 ounces is given by:
⇒ P(X> 14.6)= 1- P(z< ![\frac {14.6-14.5} \frac{{0.2}{sqrt 100}}](https://tex.z-dn.net/?f=%20%5Cfrac%20%7B14.6-14.5%7D%20%5Cfrac%7B%7B0.2%7D%7Bsqrt%20100%7D%7D%20)
⇒ 1- P(z< 5)=
⇒ 1 - 1 = 0.
Therefore,
The z score of the bags is equal to a value of zero.
