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 370 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 != r as needed. Let p be the proportion of all Canadian households with internet connections.) Ho: 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? Do not reject Ho. We can conclude that there has been a significant increase in the percentage of the Canadian households that have internet connections. Do not reject Ho. We cannot conclude that there has been a significant increase in the percentage of the Canadian households that have internet connections. Reject Ho. We can conclude that there has been a significant increase in the percentage of the Canadian households that have internet connections. Reject Ho. We cannot conclude that there has been a significant increase in the percentage of the Canadian households that have internet connections.
