For each of the following, determine whether the sampling method is independent or dependent (paired). A researcher wants to know whether the price of a one night stay at a Holiday Inn Express is less than the price of a one night stay at a Red Roof Inn. She randomly selects 8 towns where the location of the hotels is close to each other and determines the price of a one-night stay. A researcher wants to know whether the "state" quarters (introduced in 1999 for each state in the U.S.) have a mean weight that is different from "traditional" quarters. He randomly selects 18 "state" quarters and 16 “traditional" quarters and compares their weights. Do women tend to select a spouse who has an IQ higher than their own? To answer that question, researchers randomly selected 20 women and their husbands. They measured the IQ of each wife-husband team to determine whether there was a significant difference in IQ.
