She decides to ask every 12th student entering Franco starting at 8:00 AM on January 9th, “How many hours each week do you work?” She talked to 90 registered students. Sally told Susan that she worked 25 hours while John said he worked 10 hours/week. For this situation, state the:Population____________________________________Sampling method_______________________________Sample _______________________________________Data value____________________________________Statistic _______________________________________Variable Type_______________________________________4.Find a USA Today Snap Shot from a newspaper or other printed copy that uses sample descriptive statistics.
