Answer:
a) Standard deviation: 3 bluberries
b) We assume, to apply this rule, that the distribution of blueberries per muffin has a bell-curve distribution, approximately normal.
Step-by-step explanation:
We know that the number of blueberries in a blueberry muffin baked by EarthHarvest Bakeries can range from 20 to 40 blueberries.
a) If we use the Empirical Rule 68-95-99.7, specifically the last term, we have that:
- 99.7% of the data will fall between 3 standard deviations from the mean.
Then, if we consider the range of 20 to 40 containing 99.7%, we can calculate the standard deviation as:
