7392 rounded to the nearest hundred is 7400
Answer:
59.99 minutes
Step-by-step explanation:
4 hours divided by 28 mins = 8.57142857 (rounded to 8.57)
7 x 8.57 = 59.99.
A. The point estimate would be the average of the interval boundaries, which is the average of 48.2 and 56.4. This gives a point estimate of 52.3%.
b. The margin of error is the distance from either interval boundary to the point estimate. 56.4 - 52.3 = 4.1%.
c. Assuming this is solely going to be based on the class' decision, their grades should be scored on a curve. Although the margin of error is high and this seems to not have a significant distance from 50%, there is no "middle ground" in this option. We must either grade on a curve or not, and if we must choose one, we have to use to point estimate that is just slightly above 50%.
