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 higher waiting time? The 10 randomly selected patients who went to the emergency room at rural hospitals waited an average of 6.9 hours to be admitted into the hospital. The standard deviation for these 10 patients was 2.8 hours. What can be concluded at the the a = 0.05 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♥ H1: [?♥ Select an answer v c. The test statistic ?♥= (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 sv f. Based on this, we should reject the null hypothesis.
