You may need to use the appropriate appendix table or technology to answer this question. In 2012, seventy percent of Canadian households had an internet connection. A sample of 320 households taken in 2013 showed that 76% of them had an internet connection. We are interested in determining whether or not there has been a significant increase in the percentage of the Canadian households that have internet connections. (a) State the null and alternative hypotheses to be tested. (Enter != for as needed. Let p be the proportion of all Canadian households with internet connections.) H₂₂: H₂: (b) Compute the test statistic. (Round your answer to two decimal places.) (c) The null hypothesis is to be tested at the 5% level of significance. Determine the critical value(s) for this test. (Round your answer(s) to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic s test statistic 2 (d) What do you conclude? O Do not reject H. We can conclude that there…

Now that you are an adult, you decide to test one of the truisms passed along by your mother: “Cheaters never win in the end.” You randomly assign a group of 20 children to either cheat or to play fair on a scavenger hunt.
