11% of all Americans suffer from sleep apnea. A researcher suspects that a different percentage of those who live in the inner city have sleep apnea. Of the 385 people from the inner city surveyed, 23 of them suffered from sleep apnea. What can be concluded at the level of significance of a = 0.05? For this study, we should use [Select an answer The null and alternative hypotheses would be: Ho: ? Select an answer H₁: ? Select an answer (please enter a decimal) (Please enter a decimal) The test statistic? The p-value= The p-value is ? a Based on this, we should [Select an answer the null hypothesis. Thus, the final conclusion is that ... (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) The data suggest the population proportion is not significantly different from 11% 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 different from 11%. O The data suggest the populaton proportion is significantly different from 11% at a = 0.05, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is different from 11% The data suggest the population proportion is not significantly different from 11% 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 11%.
