9% of all Americans suffer from sleep apnea. A researcher suspects that a lower percentage of those who live in the inner city have sleep apnea. Of the 384 people from the inner city surveyed, 23 of them suffered from sleep apnea. What can be concluded at the level of significance of a = 0.10? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v||Select an answer v (please enter a decimal) H,: ? vSelect 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 ?Va f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the populaton proportion is significantly smaller than 9% at a = 0.10, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is smaller than 9% O The data suggest the population proportion is not significantly smaller than 9% at a = 0.10, so there is not sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is smaller than 9%. O The data suggest the population proportion is not significantly smaller than 9% at a = 0.10, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is equal to 9%. h. Interpret the p-value in the context of the study. O If the sample proportion of inner city residents who have sleep apnea is 6% and if another 384 inner city residents are surveyed then there would be a 1.96% chance of concluding that fewer than 9% of inner city residents have sleep apnea. O There is a 9% chance of a Type I error O If the population proportion of inner city residents who have sleep apnea is 9% and if another 384 inner city residents are surveyed then there would be a 1.96% chance fewer than 6% of the 384 residents surveyed have sleep apnea.
