D a confidence interval for estimating the cricket's true probability of landing on its feet is more narrow after the final 10 jumps than it was before the final 10 jumps.
<h3>What is a confidence interval of proportions?</h3>A confidence interval of proportions is given by:
In which:
is the sample proportion.
- z is the critical value.
- n is the sample size.
The margin of error is given by:
The margin of error is inversely proportional to the square root of the sample size, hence, the higher the sample size, the narrower the interval is, hence option D is correct.

<h2>Answer:</h2>
First: info on point-slope form.
- Formula: <em>y - y₁ = m(x - x₁)</em>
We need to find the slope of the line first.
Slope:
Now we can complete the point-slope equation of the line.
*These equations are equivalent.
