Question
Do the needs of patients in the emergency room differ for those who come by car vs. those by ambulance?
Of the randomly selected emergency room patients who came by car 51 had an injury, 40 were sick, 31 had
heart problems and 61 had other needs. Of the randomly selected emergency room patients who came by
ambulance 45 had an injury, 30 were sick, 55 had heart problems and 38 had other needs. Conduct the
appropriate hypothesis test using an a = 0.10 level of significance.
a. What is the correct statistical test to use?
O Paired t-test
O Homogeneity
Goodness-of-Fit
O Independence
b. What are the null and alternative hypotheses?
Ho:
O Means of transportation to the emergency room and emergency room needs are independent.
Means of transportation to the emergency room and emergency room needs are dependent.
The distribution of emergency room needs for patients who come by car is the same as it is for
patients who come by ambulance.
The distribution of emergency room needs for patients who come by car is not the same as it is
for patients who come by ambulance.
H :
The distribution of emergency room needs for patients who come by car is the same as it is for
patients who come by ambulance.
The distribution of emergency room needs for patients who come by car is not the same as it is
for patients who come by ambulance.
O Means of transportation to the emergency room and emergency room needs are dependent.
O Means of transportation to the emergency room and emergency room needs are independent.
c. The test-statistic for this data =
(Please show your answer to three decimal places.)
d. The p-value for this sample =
(Please show your answer to four decimal places.)
e. The p-value is Select an answer
f. Based on this, we should
O reject the null
O accept the null
O fail to reject the null
g. Thus, the final conclusion is...
There is sufficient evidence to conclude that the distribution of emergency room needs for
patients who come by car is the same as it is for patients who come by ambulance.
There is insufficient evidence to conclude that the distribution of emergency room needs for
patients who come by car is not the same as it is for patients who come by ambulance.
There is sufficient evidence to conclude that the distribution of emergency room needs for
patients who come by car is not the same as it is for patients who come by ambulance.
O There is sufficient evidence to conclude that the means of transportation to the emergency
room and emergency room needs are dependent.
O There is insufficient evidence to conclude that the means of transportation to the emergency
room and emergency room needs are dependent.
