Histograms, Frequency Polygons, and Time Series Graphs · Exercise 16
Suppose 111 people who shopped in a special T-shirt store were asked the number of T-shirts they own costing more than $19 each.
If the data were collected by asking the first 111 people who entered the store, then the type of sampling is:
(a) cluster
(b) simple random
(c) stratified
(d) convenience
