11% 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 317 people from the inner city surveyed, 29 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 t-test for a population mean
b. The null and altemative hypotheses would be:
Но:
v ||=

H;: PV

c. The test statistic
(please show your answer to 3 decimal places.)
d. The p-value =
e. The p-value is (? va
f. Based on this, we should Select an answer
g. Thus, the final conclusion is that ..

the null hypothesis.
The data suggest the populaton proportion is significantly smaller than 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 smaller than 11%
O The data suggest the population proportion is not significantly smaller than 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%.
O The data suggest the population proportion is not significantly smaller than 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 smaller than 11%.
h. Interpret the p-value in the context of the study.
O There is a 11% chance of a Type I error
