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.

Answer:
Part a) 
Part b) The maximum number of candy bars that you can purchase is 4
Part c) The change would be 
Step-by-step explanation:
Part a) Write an equation representing your shopping experience and use x for the number of candy bars
Let
x -----> the number of candy bars
we know that
The inequality that represent this problem is equal to
Part b) Solve the equation to determine how many candy bars can you purchase?
Solve for x
Subtract 22.95 both sides
Divide by 0.43 both sides
The maximum number of candy bars that you can purchase is 4
Part c) How much change would you have left?
If you purchase 4 candy bars
then
therefore
