Nationally, patients who go to the emergency room wait an average of 7 hours to be admitted into the hospital. Do patients at rural hospitals have a lower waiting time? The 13 randomly selected patients who went to the emergency room at rural hospitals waited an average of 6.8 hours to be admitted into the hospital. The standard deviation for these 13 patients was 1 hours. What can be concluded at the the a = 0.05 level of significance level of significance? a. For this study, we should use Select an answer b.

Question
Nationally, patients who go to the emergency room wait an average of 7 hours to be admitted into the
hospital. Do patients at rural hospitals have a lower waiting time? The 13 randomly selected patients who
went to the emergency room at rural hospitals waited an average of 6.8 hours to be admitted into the
hospital. The standard deviation for these 13 patients was 1 hours. What can be concluded at the the a =
0.05 level of significance level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Ho:
Select an answerv
H1:
v Select an answerv
c. The test statistic ?v
(please show your answer to 3 decimal places.)
%D
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 Select an answverv the null hypothesis.
g. Thus, the final conclusion is that
O The data suggest the populaton mean is significantly lower than 7 ata = 0.05, so there is
statistically significant evidence to conclude that the population mean waiting time to be
Lo
