Question

6] According to major league baseball rules, the ball must weigh between 5 and 5.25 ounces. A factory produces baseballs whose weights are normally distributed, with mean 5.11 ounces and standard deviation 0.062 ounces.

c] What proportion of the baseballs produced by this factory can be used by MLB?

d] If 8,000 baseballs are ordered, how many baseballs should be manufactured, knowing that some will need to be discarded?

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.
