A baseline and a revised count

A fictional planning note reports 80 visitors on the first day of an exhibition and 100 on the second day. The count is then corrected to 96 for the second day because four entries were duplicate records. A separate survey says that 40 percent of respondents on day one and 50 percent on day two preferred the same display, but it gives no respondent counts and does not identify a sampling method. One student reports a 20 percent rise using the original day-two count, another calls the preference difference a 10 percent increase, and another assumes all visitors completed the survey. The exercise asks for a revised count comparison and a careful statement about the preference percentages. It supplies no real exhibition statistics or evidence that a display change caused either difference.
