Suppose a random sample of 110 U. S. companies taken in 2015 showed that 68 offered high-deductible health insurance plans to their workers. A separate random sample of 120 firms taken in 2019 showed that 63 offered high-deductible health insurance plans to their workers. Based on the sample results, can you conclude that there is a lower proportion of U. S. companies offering high-deductible health insurance plans to their workers in 2019 than in 2015
