In a large economics class, the professor announced that the scores of a recent exam were normally distributed in a domain from 51 to 87. Using the Empirical Rule on µ ± 3σ to estimate σ (that is, σ=[upper limit-lower limit]/6), how many students would you need to sample in order to construct a 90 percent confidence interval of the population mean score with an allowable error of ± 2? (Hint: use the critical value Z0.05=1.645 for a 90 percent...
Consider the data presented below of a dataset of midterm exam scores from last year’s stats class. Do the following: Group them into a frequency distribution employing a class width of i = 10. Create a summary table showing: The class intervals The upper and lower real limits of each class interval The midpoints of each class interval The grouped frequency distribution of each class interval The cumulative frequency for each class interval The cumulative proportion of each class interval...
