Question

Mr. Coca-Cola wishes to estimate the mean volume of all the 12-ounce bottles in his plant using a 99% CI.
[Prof. Gersch again notes that people should be drinking healthier beverages instead!]

He assumes that the volume of all the bottles is normally distributed with a standard deviation of 0.5 ounces.
How big should his sample size be so that is margin of error is no larger than 0.2 ounces?

	a.	25
	b.	12
	c.	41
	d.	7
	e.	42
	f.	24

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.
