According to Pew Research Center surveys, 12% of American adults did not own a cell phone in 2012. Suppose Verizon Wireless would like to test if this percentage has recently changed. A recent random sample of 280 American adults was selected, and it was found that 29 of them did not own a cell phone. Using ? = 0.10, answer the following: a. What type of test will be used and what distribution? b. Based on this sample and using the 6 hypothesis steps, what conclusions can Verizon Wireless make about this population?
