Using the normal distribution, it is found that there is a 0.0013 = 0.13% probability that the mean weight of 25 pods of coffee is less than 42.035 grams.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation .
The parameters are given as follows:
The probability that the mean weight of 25 pods of coffee is less than 42.035 grams is the <u>p-value of Z when X = 42.035</u>, hence:
Z = -3
Z = -3 has a p-value of 0.0013.
0.0013 = 0.13% probability that the mean weight of 25 pods of coffee is less than 42.035 grams.
