Chapter 10.2, Problem 10.16ACI

Cell phone user survey. If you subscribe to a cell phone plan, how many different cell phone numbers do you own? This was one question of interest in Public Opinion Quarterly (Vol. 70, No. 5, 2006). According to the Current Population Survey (CPS) Cell Phone Supplement, 51% of cell phone plans have only one cell number, 37% have two numbers, 9% have three numbers, and 3% have four or more numbers. An independent survey of 943 randomly selected cell phone users found that 473 pay for only one number, 334 pay for two numbers, 106 pay for three numbers, and 30 pay for four or more numbers. Conduct a test to determine if the data from the independent survey contradict the percentages reported by the CPS Cell Phone Supplement. Use α = .01.
