Question

"DRUGS R US" is a large manufacturer of various kinds of liquid vitamins.
The quality control department has noted that the bottles of vitamins
marked 6 ounces vary in content with a standard deviation of 0.3 ounces.
Many random samples of 100 bottles is taken. Assume the contents of
the bottles are normally distributed with a mean of 6 ounces.
Approximately 33% of the random samples will have bottles containing at
least how many ounces of the vitamins? (final to 4 decimal places)

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
