We are interested in estimating the proportion of people that can identify Nebraska but not Vermont. In a class of 55 students, each student was requested to select a sample of 6 people, show each person a map of the US and ask the person to identify the states of Vermont and Nebraska. The following numbers are the counts that each student got, that is, each number is the count of people in the student sample of 6, that could identify Nebraska but not Vermont.2233010110020030002020001100002010000001000200000001010Note: You can cut and past these numbers into an excel spreadsheet to help you calculate the mean and the standard deviation and compute the confidence interval.

A study of n = 2252 adults age 18 or older found that 72% of the cell phone users send and receive text messages.15 A study of n = 800 teens age 12 to 17 found that 87% of the teen cell phone users send and receive text messages. What is the best estimate for the difference in the proportion of cell phone users who use text messages, between adults (defined as 18 and over) and teens? Give notation (as a difference with a minus sign) for the quantity we are trying to estimate, notation for the quantity that gives the best estimate, and the value of the best estimate. Be sure to clearly define any parameters in the context of this situation.

The manager of a local record store is interested in the effectiveness of an advertising campaign on sales. They randomly select 10 popular CDs (all in the Billboard top 100) and place an ad in the local school newspaper saying that the store has these (and more) in stock. They measure the sales of these 10 CDs for 1 week prior to the ad, and then for 1 week after the ad. The number of CDs sold each week is presented below.
