The answer to this question is 2 and 2/3
Answer:
0.5 is part of the confidence interval, and thus, it is reasonable to believe more than half of food delivery drivers eat some of the food they are delivering.
Step-by-step explanation:
95% confidence interval for the true proportion of food delivery drivers who eat some of the food they are delivering is (0.398, 0.706).
This means that we are 95% sure that the true proportion of food delivery drivers who eat some of the food they are delivering is (0.398, 0.706).
Is it reasonable to believe more than half of food delivery drivers eat some of the food they are delivering?

Answer:
the slope of the line is the angle at which it slants
Step-by-step explanation:
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:
