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<
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<
⇒ 1- P(z< 5)=
⇒ 1 - 1 = 0.
Therefore,
The z score of the bags is equal to a value of zero.
