Answer:
c = 26
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem.
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
10^2 + 24^2 = c^2
100 + 576 = c^2
676 = c^2
Take the square root of each side
sqrt(676) = sqrt(c^2)
26 = c
Answer:
d. The width of Elly's interval will be less than the width of Drew's interval.
Step-by-step explanation:
The confidence level and the width of the confidence interval are direct proportional. This means that a confidence interval with a higher confidence level has a higher width.
For example, a 99 percent confidence interval is wider than a 90 percent confidence interval.
The midpoint of the confidence interval is the mean of the population, no matter the confidence level.
In this problem, we have that:
Elly: 90 percent CI
Drew: 99 percent CI
The correct answer is:
d. The width of Elly's interval will be less than the width of Drew's interval.
