A separate random sample of 110 firms tak 2007 showed that 29 offered high-deductible health insurance plans to their workers. Based on the sample results, can you conclude that there is a higher proportion of companies offe high-deductible health insurance plans to their workers in 2007 than in 2006? Conduct your hypothesis test at a level of significance a = 0.01. Let p, be the population proportion from 2007, and let p, be the population proportion from 2006. Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: P1- P2
