The weight of crackers in a box is stated to be 450 grams.The amount that the packaging machine puts in the boxes is believed to have a Normal model with mean 465 grams and standard deviation 30 grams.What is the probability that the mean weight of a 50−box50 - \mathrm { box }50−box case of crackers is below 450 grams?
A) 0.9998
B) 0.9996
C) 0.0015
D) 0.0002
E) 0.0004
Normal Model
A type of statistical distribution that is symmetric, bell-shaped, and describes how continuous data points are dispersed or spread across the mean.
Crackers
A thin, crisp biscuit often made from flour and water that can be salted or savory, and is commonly served with cheese or other spreads.
Standard Deviation
A statistical measure of the dispersion or variability within a dataset, indicating how spread out the data points are from the mean.
