The empirical rule for normal distributions states that approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean.
The answer is 68%.

68% percentage of the balls weigh within one standard deviation of the mean. Option b is correct.

The weights of tennis balls are normally distributed, with the mean being 5.15 ounces and the standard deviation being 0.10. what percentage of the balls weigh within one standard deviation of the mean to be determined.

What is the empirical rule?

Empirical Rule is defined as an elongation of the prior reading Understanding the Normal Distribution. In the prior reading, the aim was to develope an instinct of the relations between lowered probability and expanded distance from the mean.

Since, from the empirical rule, it can be said that 68% percent of the balls weigh within one standard deviation of the mean because Approx 68% of the data occurs within 1 Standard Deviation of the mean.

Thus, 68% percentage of the balls weigh within one standard deviation of the mean. Option b is correct.
