Answer:
60
Step-by-step explanation:
The function provided is:

The average rate of change of h(t) as time goes from t=a to t=b is expressed as:

This function can be reformulated as: 
The rocket's peak height is 231, which occurs at t=3.75 seconds.

The initial launch happens at: t=0
and 
The average rate of change from launch to max height is

Four statements:
1) Start by dividing the x-axis into equal segments.
2) n = 212/5 = 42.4.
3) Each segment along the x-axis represents 42.4. This means you can plot the point -212 at x = -5
4) The y-axis can keep its magnitude and you can plot the coordinate of -4 at y = -4
I couldn't write it out in detail, so the solution is 200. The work is visible in the image below if you need clarification. I hope this is useful to you!
Response:
The conclusion drawn by the scientist is flawed because it relies on a subjective assessment ("significantly greater than").
What is meant by “significantly greater”?
A more objective and precise method would involve establishing a significance level, for example, 0.05 or 0.01, to compute the sample means and standard deviations, and then conducting appropriate hypothesis testing to determine whether the mean differences are indeed significant.
