13% of all Americans suffer from sleep apnea. A researcher suspects that a higher percentage of those who live in the inner city have sleep apnea. Of the 359 people from the inner city surveyed, 65 of them suffered from sleep apnea. What can be concluded at the level of significance of a = 0.05? a. For this study, we should use |Select an answer b. The null and alternative hypotheses would be: Ho: ? Select an answer v (please enter a decimal) H1 : ? Select an answer v (Please enter a decimal) c. The test statistic ? v = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? v a f. Based on this, we should Select an answer w | the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the populaton proportion is significantly larger than 13% at o - 0.05, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is larger than 13% The data suggest the population proportion is not significantly larger than 13% at a - 0.05, so there is not sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is larger than 13%. The data suggest the population proportion is not significantly larger than 13% at a = 0.05, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is equal to 13%. h. Interpret the p-value in the context of the study. If the population proportion of inner city residents who have sleep apnea is 13% and if another 359 inner city residents are surveyed then there would be a 0.2% chance that more than 18% of the 359 inner city residents surveyed have sleep apnea. If the sample proportion of inner city residents who have sleep apnea is 18% and if another 359 inner city residents are surveyed then there would be a 0.2% chance of concluding that more than 13%% of all inner city residents have sleep apnea. There is a 0.2% chance of a Type | error. There is a 0.2% chance that more than 13% of all inner city residents have sleep apnea. i. Interpret the level of significance in the context of the study. If the population proportion of inner city residents who have sleep apnea is 13% and if another 359 inner city residents are surveyed then there would be a 5% chance that we would end up than 13%. falsely concluding that the proportion of all inner city residents who have sleep apnea is larger There is a 5% chance that aliens have secretly taken over the earth and have cleverly disguised themselves as the presidents of each of the countries on earth. larger than 13%. There is a 5% chance that the proportion of all inner city residents who have sleep apnea is If the population proportion of inner city residents who have sleep apnea is larger than 13% and if another 359 inner city residents are surveyed then there would be a 5% chance that we would end up falsely concluding that the proportion of all inner city residents who have sleep apnea is equal to 13%
