Answer:
44
Step-by-step explanation:
Given that Krutika gets 33 sweets which is 3 parts of the ratio.
Divide this amount by 3 to find the value of one part of the ratio
33 ÷ 3 = 11 ← 1 part of the ratio, thus
David gets 1 × 11 = 11 sweets and
Mark gets 5 × 11 = 55 sweets, thus
55 - 11 = 44 ← number of sweets Mark gets over David
Answer:
Error Bound = 0.04
Step-by-step explanation:
Whenever we want to estimate parameter from a subset (or sample) of the population, we need to considerate that your estimation won't be a 100% precise, in other words, the process will have a random component that prevents us from always making the exact decision.
With that in mind, the objective of a confidence interval is to give us a better insight of where we expect to find the "true" value of the parameter with a certain degree of certainty.
The estivamative of the true difference between proportions was -0.19 and the confidence interval was [-0.23 ; -0.15].
The question also defines the error bound, as the right endpoint of the confidence interval minus the sample mean difference, so it's pretty straight foward:
Error Bound =
The interpretation of this would be that we expect that the estimative for the difference of proportions would deviate from the "true" difference about or 4%.
