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%.
Answer:
Step-by-step explanation:
Just choose something to show, like miles ran, or balls shot. Then just use the ratio, like in the example. GL!
Answer:
y=3
Step-by-step explanation:
RT = BT = 75
This is because she used the same angle from point C to mark point B, thus creating a symmetric right triangle.
Triangle BCT = Triangle RCT
