The final exam score was recorded for each Harper statistics student in a sample of 30. A 95% confidence interval for is (152, 156) points. a.) The individual object in the study was a randomly selected _____. This is computer-graded so use exact wording from the problem above. b.) What was the variable information recorded for each object in the study? This is computer-graded so use exact wording from the problem above. c.) State the statistical interpretation of the confidence interval in the context of this problem. Select an answer 95% of the time There is a 95% chance that We are 95% confident that the final exam score of ? 30 all Harper statistics student is/are between and d.) What is the symbol and value of the point estimate for ? ? X p n p s X N = points e.) What is the margin of error for the given interval? points

Remember: the sample statistic is the midpoint of the confidence interval, and the difference between the highest and lowest value of your interval (its width) is the two times the margin of error. f.) Fill in the boxes below to show the relation on the number line between the numeric values of the point estimate and the interval estimate for . <--------A--------------B--------------C--------> A = B = C =
