Answer:
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
If the bottles are 8 ounces, what value of µ would give us a 1% probability of putting more than 8 ounces in a bottle (overflowing) normal distribution
This means that Z when X = 8 has a pvalue of 1-0.01 = 0.99. So when X = 8, Z = 2.33.
