a) Describe an example of a real-world situation in which sampling without replacement makes sense.
b) How would an 80% confidence interval compare to a 99% confidence interval?
c) What is the advantage of using pivotal confidence intervals instead of percentile confidence intervals?
Homework Answers
a) while surveying the students of a college for the mode of income they had we would select students randomly without replacement as we dont want to select the same student and record their readings.
b) 80% confidence interval is narrower than 99% confidence interval . Thus it is more likely that 99% confidence interval will contain the true value.
C) pivotel confidence interval is more exact and accurate than percentile confidence interval

Describe a real-life example of conformity in ambiguous reality. What makes it ambiguous reality? Describe a real-life example of conformity in clear reality. What makes it clear reality? (don’t use research studies to answer- make sure you use an original example of a real-life situation). How could you either reduce or increase conformity in these situations?

a) Approximately 500 students take a particular college statistics course each year. As an exercise, each of the 500 students in the class is given a different random sample of the previous year's 500 final grades (in percentages) and asked to construct a 95% interval estimate of the previous year's overall average. Which of the following statements is correct? About 475 of the confidence intervals will contain the actual overall average for the previous year. It is probable that 475...

A researcher wanted to study the effect of a newly developed gasoline additive (Additive X) on automobile mileage (miles per gallon, MPG). To gather information, a random sample of cars has been selected. For each car, the MPG was measured both when gasoline with Additive X is used and when gasoline without Additive X is used. The order of the two treatments (with Additive X versus without Additive X) was randomized and care was taken so that there was no...

Recall that the formula for a confidence interval is Statistc + MOE. Next you will need to interpret the confidence interval. The interpretation of a confidence interval should always include 3 things: the level of confidence, reference to the parameter in context and the calculated interval. Notice that the only difference between this worksheet and the calculating confidence intervals worksheet from module 8 is that you now need to calculate the margin of error. 1. Suppose that a recent study...
