Nationally, patients who go to the emergency room wait an average of 4 hours to be
admitted into the hospital. Do patients at rural hospitals have a different waiting time? The
11 randomly selected patients who went to the emergency room at rural hospitals waited
an average of 2.7 hours to be admitted into the hospital. The standard deviation for these
11 patients was 2.8 hours. What can be concluded at the the a = 0.10 level of significance
level of significance?
a. For this study, we should use t-test for a population mean
b. The null and alternative hypotheses would be:
Ho: ?v Select an answer v
H1:
?v Select an answer v
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 reject
g. Thus, the final conclusion is that ...
v the null hypothesis.
The data suggest that the population mean awaiting time to be admitted into
the hospital from the emergency room for patients at rural hospitals is not
significantly different from 4 hours at a = 0.10, so there is statistically
insignificant evidence to conclude that the population mean waiting time to be
admitted into the hospital from the emergency room for patients at rural
hospitals is different from 4 hours.
O The data suggest the population mean is not significantly different from 4 at a
= 0.10, so there is statistically insignificant evidence to conclude that the
population mean waiting time to be admitted into the hospital from the
emergency room for patients at rural hospitals is equal to 4 hours.
