Question

In a sample of 85 large grade aa eggs, the mean number of calories was 80 with a standard deviation of 2.7. In a sample of 90 large grade a eggs, the mean number of calories was 70 with a standard deviation of 2.5. What is the difference in the mean number of calories between the two samples?

Answer 1

The difference in the mean number of calories between the two samples of large grade AA and A eggs is 10 calories.

Step-by-step explanation:

The difference in the mean number of calories between two samples of eggs can be calculated simply by subtracting the mean of one sample from the mean of the other. For the large grade AA eggs with a mean of 80 calories and the large grade A eggs with a mean of 70 calories, the difference is:

80 calories (grade AA) - 70 calories (grade A) = 10 calories

Therefore, the difference in the mean number of calories between the two samples is 10 calories.
