Phineas Phillips, from Philadelphia, has a fascination with fun phone facts. But Phineas has furrowed his brow because his cousin Felix (from Florida) claims to have a phone fact that Phineas is not familiar with. His cousin claims that the percentage of iPhone users in Canada is different than it is in the United States. Phineas knows (for a fact) that the percentage of smart phone users in the US that prefer iPhones is 45%. A random sample of 400 Canadian smart phone users indicates that 160 of them prefer iPhones. Can Phineas conclude, at a 10% level of significance that the percent of iPhone users in the US is different than it is in Canada? What is the null hypothesis? What is the alternate hypothesis? Is this a left tail, right tail, or two tailed test? What is the value of the test statistic? What is your conclusion for the hypothesis test?
