[2] a] "I work at the tness center. For the next 3 shifts I'll sample every 5'\" person who uses the tness center. If that doesn't get to 60, I'll extend it to the 4'\" and 5\"1 shift as needed. "' b} \"I will have the registrar's ofce to use a random number generator to select ED students from a list arranged by ID number. " c] " I am taking 4 classes and each class has at least 15 students.

Data was collected on colleg. Two variables {both categorical] were type of college {public v. private] and whether the college had an increase or decrease in enrollment. What would be an appropriate way to organize and display this data: [2] a] Use a two way table b} Use a scatterplot c] Use a boxplot d} Make a side I; side dotplot In bootstrapping, the original sample is used to create bootstrap samples. If the original sample was {12, 15, 13, 19, 13}, circle all of the following that could be bootstrap samples: [2] a] {12, 12, 15, 1a, 15} b} {12, 1a, 15} c] {10, 11, 2a, 25, la, 15, 15, 1a, 15, ID} d} {12, 15, 15, 15, 15}
