10% 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 361 people from the inner city surveyed, 40 of them suffered from sleep apnea. What can be concluded at the level of significance of αα = 0.10? For this study, we should use? Select an answer: z-test for a population proportion or t-test for a population mean? The null and alternative hypotheses would be: Ho: p or μ? Select an answer: > < ≤ ≠ = ≥? ________ (please enter a decimal) H1: μ or p? Select an answer :≥ > = < ≠ ≤? ________ (Please enter a decimal) The test statistic z or t? =_______ (please show your answer to 3 decimal places.) The p-value = ________ (Please show your answer to 4 decimal places.) The p-value is ? ≤ or > Based on this, we should Select an answer reject? accept? or fail to reject? the null hypothesis. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly larger than 10% at αα = 0.10, so there is not sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is larger than 10%. The data suggest the populaton proportion is significantly larger than 10% at αα = 0.10, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is larger than 10% The data suggest the population proportion is not significantly larger than 10% at αα = 0.10, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is equal to 10%. Interpret the p-value in the context of the study. There is a 24.69% chance that more than 10% of all inner city residents have sleep apnea. If the population proportion of inner city residents who have sleep apnea is 10% and if another 361 inner city residents are surveyed then there would be a 24.69% chance that more than 11% of the 361 inner city residents surveyed have sleep apnea. If the sample proportion of inner city residents who have sleep apnea is 11% and if another 361 inner city residents are surveyed then there would be a 24.69% chance of concluding that more than 10% of all inner city residents have sleep apnea. There is a 24.69% chance of a Type I error. Interpret the level of significance in the context of the study. If the population proportion of inner city residents who have sleep apnea is larger than 10% and if another 361 inner city residents are surveyed then there would be a 10% chance that we would end up falsely concluding that the proportion of all inner city residents who have sleep apnea is equal to 10%.

Question

For this study, we should use? Select an answer: z-test for a population proportion or t-test for a population mean?
The null and alternative hypotheses would be:
Ho: p or μ? Select an answer: > < ≤ ≠ = ≥? ________ (please enter a decimal)
H₁: μ or p? Select an answer :≥ > = < ≠ ≤? ________ (Please enter a decimal)

The test statistic z or t? =_______ (please show your answer to 3 decimal places.)
The p-value = ________ (Please show your answer to 4 decimal places.)
The p-value is ? ≤ or >
Based on this, we should Select an answer reject? accept? or fail to reject? the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the population proportion is not significantly larger than 10% at αα = 0.10, so there is not sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is larger than 10%.
- The data suggest the populaton proportion is significantly larger than 10% at αα = 0.10, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is larger than 10%
- The data suggest the population proportion is not significantly larger than 10% at αα = 0.10, so there is sufficient evidence to conclude that the population proportion of inner city residents who have sleep apnea is equal to 10%.
Interpret the p-value in the context of the study.
- There is a 24.69% chance that more than 10% of all inner city residents have sleep apnea.
- If the population proportion of inner city residents who have sleep apnea is 10% and if another 361 inner city residents are surveyed then there would be a 24.69% chance that more than 11% of the 361 inner city residents surveyed have sleep apnea.
- If the sample proportion of inner city residents who have sleep apnea is 11% and if another 361 inner city residents are surveyed then there would be a 24.69% chance of concluding that more than 10% of all inner city residents have sleep apnea.
- There is a 24.69% chance of a Type I error.
Interpret the level of significance in the context of the study.
- If the population proportion of inner city residents who have sleep apnea is larger than 10% and if another 361 inner city residents are surveyed then there would be a 10% chance that we would end up falsely concluding that the proportion of all inner city residents who have sleep apnea is equal to 10%.
- If the population proportion of inner city residents who have sleep apnea is 10% and if another 361 inner city residents are surveyed then there would be a 10% chance that we would end up falsely concluding that the proportion of all inner city residents who have sleep apnea is larger than 10%.
- There is a 10% chance that aliens have secretly taken over the earth and have cleverly disguised themselves as the presidents of each of the countries on earth.
- There is a 10% chance that the proportion of all inner city residents who have sleep apnea is larger than 10%.
