Question 1 Test the claim that the mean GPA of night students is significantly different than 2.3 at the 0.05 significance level. The null and alternative hypothesis would be: Ho:p 2 0.575 Ho:u 2.3 Hi :p 2.3 H1:p / 0.575 H1:u # 2.3 H1 :p > 0.575 H1:M 0.6 H1 :p 2.4 The test is: right-tailed left-tailed two-tailed Based on a sample of 35 people, the sample mean GPA was 2.35 with a standard deviation of 0.05 The test statistic is: (to 2 decimals) The p-value is: (to 2 decimals) Based on this we: O Fail to reject the null hypothesis O Reject the null hypothesis Question Help: Message instructor Submit Question0 Question 3 v 21.21 0 ,1 > 21.21 Op - nonzerorands expects 3 arguments 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 different waiting time? The 15 randomly selected patients who went to the emergency room at rural hospitals waited an average of 3.7 hours to be admitted into the hospital. The standard deviation for these 15 patients was 2.6 hours. What can be concluded at the the a = 0.10 level of significance level of significance? a. For this study, we should b. The null and alternative hypotheses would be: H0: H1: Select an answerv c. The test statistic = (please show your answer to 3 decimal places.) . The p-value = (Please show your answer to 4 decimal places.) . The p-value is or . Based on this, we should the null hypothesis. . Thus, the final conclusion is that mthD. O The data suggest the populaton mean is significantly different from 4 at a = 0.10, 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 different from 4 hours. 0 The data suggest the population mean is not significantly different from 4 at a = 0.10, 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 equal to 4 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 different from 4 hours at as = 0.10, 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 different from 4 hours.
