Researchers conducted two surveys about teens are their use of social media. The first survey asked a random sample of 800 U.S. teens about their use of Instagram. A second survey asked the same questions to a random sample of 2253 Canadian teens. In these two studies, 73% of U.S. teens and 88% of Canadian teens said that they use Instagram. Use these results to answer the following questions about the proportion of U.S. and Canadian teens that use Instagram. Is there a statistically significant difference between the use of social media by U.S. teens and Canadian teens? No, there is no difference between the proportion of U.S. teens that use Instagram and the proportion of Canadian teens that use Instagram because both the lower limit and the upper limit of the confidence interval are negative values. Yes, the proportion of U.S. teens that use Instagram is significantly less than the proportion of Canadian teens that use Instagram difference because both…
Insurance componies track life expertancy info to assist in determining the cost of life insurance polocies. The insurance compony knows that last year the life expectancy of its polocy holders was 77 years. They want to know if their clients this year have a longer life expectancy, on average, so the company randomy samples some of the recently paid polices to see if the mean life expectancy of polcy holders has increased. Sample: 86,75, 83, 84, 81, 77, 78, 79, 79,81, 76, 85, 70,76, 79,81, 73, 74, 72, 83. 1) Does this sample indicate that the insurance company should change its premiums because life expectancy has increased? 2) For more accurate cost determination, the insurance companies want to estimate the life expectancy to within one year with 95% confidence.
