The option that describes the relationship between the two confidence intervals is; The width of I₈₁ will be¹/₉ the width of I₉
<h3>How to calculate width of the confidence interval with normal distribution?</h3>
The width of the confidence interval will be calculated from the formula;
W = 2Z(σ/√n)
where;
z is the z-score at given confidence level
σ is standard deviation
n is sample size
For first sample;
W_i9 = 2Z(σ/√9)
W_i9 = ²/₃Zσ
For second Sample;
W_i81 = 2Z(σ/√81)
W_i81 = ²/₉Zσ
Thus, we will have;
W_i9/W_i81 = (²/₃Zσ)/(²/₉Zσ)
W_i9/W_i81 = 9
W_i81 = ¹/₉W_i9

It's not A or B. And between C and D, I'd choose flexible schedules. <span />
Answer:
B -moderate
Explanation:
because due to the average amount of people who scored , she can identify the remaining by dividing by 2
The Best Option Would Be D Because British Museum-Egyptian Pyramids Would Be Helpful, But National Geographic:Egyptian Pyramids, Facts, Photos, And Diagrams Has That And More. C I Wouldn't Find Very Helpful, Because It's Just Focused On Pyramids, And B Is Totally Out Of The Picture. Hope That Helps!
