Question

Use the Empirical Rule to determine the percentage of candies with weights between 0.7 and 0.98 gram. ​Hint: x=0.84

Answer 1

Using the Empirical Rule, it is found that 95% of the candies have weights between 0.7 and 0.98 gram.

What does the Empirical Rule state?

It states that, for a normally distributed random variable:

• Approximately 68% of the measures are within 1 standard deviation of the mean.

• Approximately 95% of the measures are within 2 standard deviations of  the mean.

• Approximately 99.7% of the measures are within 3 standard deviations of the mean.

Researching this problem on the internet, we have that:

• The mean is of 0.84.

• The standard deviation is of 0.07.

Then 95% of the candies have weights between 0.7 and 0.98 gram, as:

• 0.7 = 0.84 - 2 x 0.07.

• 0.98 = 0.84 + 2 x 0.07.
