A test was given to n= 52 students. Their scores are charted in the grouped frequency histogram shown. Answer questions 8-9 based on this diagram. Frequency Histogram for Test Frequency 10 8 6 4 2 0 35 40 45 50 55 60 65 70 75 80 85 90 95 Test Scores Which of the following could be the percentile rank associated with the highest score in the interval whose midpoint is 60? 3rd 4th 13th 25th

Step 1
Since we don't have the exact frequency distribution, we can only estimate the percentile rank. Let's assume that the interval with a midpoint of 60 has a frequency of f. Then, the cumulative frequency up to this interval would be the sum of the frequencies of Show more…

For a particular sample of 50 scores on a statistics exam, the following results were obtained: mean = 78, median = 80, mode = 84, range = 52, Q1 = 68, Q3 = 92, standard deviation = 11. What score was earned by more students than any other score?
