The correct option is B.
Thus, 68% percentage of the balls weigh within one standard deviation of the mean.
<h3>What is the empirical formula rule?</h3>
The Empirical Rule indicates that 99.7% of data that are observed to have a normal distribution fall within 3 standard deviations of the mean. According to this formula, 68 percent of the data are within one standard deviation, 95 percent are within two standard deviations, and 99.7 percent are within three standard deviations of the mean.
<h3>According to the empirical formula rule:</h3>
Because approximately 68% of the data falls within a standard deviation of the mean, according to the empirical rule, 68% of the balls' weights fall within that range.

I understand that the question you are looking for is:
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
A. 50%
B. 68%
C. 95%
D. 99.7%
Answer:
No solution unless you put in the wrong equations
Step-by-step explanation:
Answer:
The mistake there is the expression shown is not in PEMDAS.
<em>PEMDAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on multiplication & division and at last addition and subtraction.</em>
Step-by-step explanation:
1 + 4 x 9 4 x 9 = 36
1 + 36 36 + 1 = 37
37
Always remeber to use multiplication first!
