Nationally, patients who go to the emergency room wait an average of 5 hours to be admitted into the hospital. 00 patients at rural hospitals have a higher waiting time? The 15 randomly selected patients who went to the emergency room at rural hospitals waited an average of 6 hours to be admitted into the hospital. The standard deviation for these 15 patients was 1.1 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 V b. The null and alternative hypotheses would be: d e .h . The test statistic . The p-value = C] (Please show your answer to 4 decimal places.) . The p-value is . Based on this, we should the null hypothesis. . Thus, the final conclusion is that Selectan answer V C] Selectan answer V |:] = C] [please show your answer to 3 decimal places.) O The data suggest the populaton mean is signicantly higher than 5 at a = 0.05, so there is statistically significant 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 higher than 5 hours. 0 The data suggest the population mean is not significantly higher than 5 at a = 0.05, so there is statistically insignificant evidence to conclude that the population mean waiting time to he admitted into the hospital from the emergency room for patients at rural hospitals is equal to 5 hours. 0 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 higher than 5 hours at a = 0.05, 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 higher than 5 hours
