The rate of change for the interval between 2 and 6 on the x-axis is 3.
Given
On a coordinate plane, a parabola opens up.
Solid circles appear on the parabola at (negative 4, 14), (negative 3, 9. 5), (negative 2, 6), (0, 2), (1, 1. 5), (2, 2), (4, 6), (5, 9. 5), (6, 14).
<h3>What is the rate of change?</h3>A rate of change defines how one quantity changes in relation to another quantity.
The rate of change for the interval between 2 and 6 on the x-axis is;
Hence, the rate of change for the interval between 2 and 6 on the x-axis is 3.

Answer:
Step-by-step explanation:
Given that a researcher is trying to decide how many people to survey.
We have confidence intervals are intervals with middle value as the mean and on either side margin of error.
Confidence interval = Mean ± Margin of error
Thus confidence interval width depends on margin of error.
Margin of error =
Thus for the same confidence level and std deviation we find margin of error is inversely proportional to square root of sample size.
Hence for small n we get wide intervals.
So if sample size = 300, the researcher will get wider confidence interval
