### Hypothesis Testing Exercise #### Hypothesis Statement - **\( H_1 \):** The alternative hypothesis options are: - The distribution of emergency room needs for patients who come by car is the same as it is for patients who come by ambulance. - 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 not the same as it is for patients who come by ambulance. #### Statistical Testing Steps **c.** Compute the test statistic for the data. Input your answer with three decimal places. - **Test-statistic for this data =** [Input box] **d.** Determine the p-value for this sample. Input your answer with four decimal places. - **P-value for this sample =** [Input box] **e.** Evaluate the p-value in relation to alpha (α). - **The p-value is:** [Select an option] α #### Conclusion **f.** Based on the results, we should: - Accept the null - Reject the null - Fail to reject the null **g.** Final conclusion based on the hypothesis test: - 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 insufficient evidence to conclude that the means of transportation to the emergency room and emergency room needs are dependent. - There is sufficient evidence to conclude that the means of transportation to the emergency room and emergency room needs are dependent. - 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.

**Analysis of Emergency Room Needs Based on Transportation** This section examines whether the needs of emergency room patients differ depending on their mode of transportation: car vs. ambulance. **Data Summary:** - **Patients who came by car:** - Injury: 54 - Sickness: 53 - Heart problems: 37 - Other needs: 67 - **Patients who came by ambulance:** - Injury: 45 - Sickness: 22 - Heart problems: 43 - Other needs: 30 A hypothesis test will be conducted with a significance level of α = 0.01. **Questions:** **a. What is the correct statistical test to use?** - Options: - Homogeneity - Goodness-of-Fit - Independence - Paired t-test **b. What are the null and alternative hypotheses?** **\( H_0 \):** - Options: - Means of transportation to the emergency room and emergency room needs are independent. - 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. - Means of transportation to the emergency room and emergency room needs are dependent. The analysis will involve choosing the appropriate statistical test and formulating hypotheses to determine the correlation between transportation means and patient needs in an emergency room setting.
