QUESTION 1 1. C10 Q10 V3: The Excel le STATISTICSSTUDENTSSURVEYFORR contains the column ENDPULSEMIN (a numerical variable that measures student pulses after completing an online survey] and the column BEFPULSEMIN (a numerical variable that measures student pulses before completing an online survey]. For education purposes, consider this dataset to be a sample of size 60 taken from a much larger population for statistics students. Consider the paired differences d=ENDPULSEMlN - BEFPULSEMIN. Calculate a 90% confidence interval for the mean of the population paired differences. Choose the most correct answer. r. Your condence interval is (0.5612735, 1.43 87265] and there is no signicant evidence that, on average, the two pulse rate measurements give different results, on average. Your condence interval is (0.4746613, 1.52 53387] and there is signicant evidence that, on average, the two pulse rate measurements give different results. r. r. Your condence interval is (0.5612735, 1.43 87265] and there is signicant evidence that, on average, the two pulse rate measurements give different results. r. Your condence interval is (0.4746613, 1.52 53387] and there is no signicant evidence that, on average, the two pulse rate measurements give different results. 1 points QUESTION 2 1. C10 Q2 V3: The Excel file STATISTICSSTUDENTSSURVEYFORR contains the column ENDBREATHMIN (a numerical variable that measures student breaths per minute after completing an online survey] and the column BEFBREATHMIN (a numerical variable that measures student breaths per minute before completing an online survey]. For education purposes, consider this dataset to be a sample of size 60 taken from a much larger population for statistics students. Consider the paired differences d=ENDBREATHMIN - BEFBREATHMIN. You wish to test whether there is signicant evidence , on average, ENDBREATHMIN are greater than BEFBREATHMIN with a signicance level of 5%. Choose the correct statement below. F You should test Ho: pd c: 0 versus Ha: pd > 0 and you will fail to reject Ho You should test Ho: pd > = 0 versus Ha: pd = 0 and you will reject Ho F You should test Ho: pd > 0 versus Ha: pd c = 0 and you will fail to reject Ho 1 points QUESTION 3 1. C10 Q3 V1: The Excel file STATISTICSSTUDENTSSURVEYFORR contains the column ENDPULSEMIN (a numerical variable that measures student pulses after completing an online survey] and the column BEFPULSEMIN (a numerical variable that measures student pulses before completing an online survey]. For education purposes, consider this dataset to be a sample of size 60 taken from a much larger population for statistics students. Consider the paired differences d=ENDPULSEMlN - BEFPULSEMIN. You wish to test whether there is signicant evidence that the post-survey bpm differ from pre-survey bpm, on average. Use a level of signicance of 5%. Which of the following statements is most correct. (- Your test statistic is 3.8090 and you reject your Ho. Your test statistic is 3.8090 and you fail to reject your Ho. Your test statistic is -3.8090 and your reject your Ho. '3')": Your test statistic is -3.8090 and you fail to reject your Ho. 1 points QUESTION 4 1. C10 Q11 V2 The Excel file STATISTICSSTUDENTSSURVEYFORR contains the column YRAGE (a numerical variable that measures student age in years) and the column RNGOOD (a categorical variable that measures whether the student feels Rachel Notley is doing a good job (No, Yes) ). For education purposes, assume that the two groups are two independent samples from a much larger normal population for statistics students. Using the difference uNo- uYes, calculate the appropriate 90% two sided confidence interval for the difference, on average, of the student ages in years for the No and Yes groups. Choose the most correct answer below. O Your confidence interval is (-2.6357319, 0.1268033) and there is significant evidence that no and yes groups have significantly different ages, on average O Your confidence interval is (-2.6357319, 0.1268033) and there is no significant evidence that no and yes groups have significantly different ages, on average. O Your confidence interval is (-2.9108604, 0.4019318) and there is significant evidence that no and yes groups have significantly different ages, on average. O Your confidence interval is (-2.9108604, 0.4019318) and there is no significant evidence that no and yes groups have significantly different ages on average. 1 points QUESTION 5 1. C10 Q7 V3: The Excel file STATISTICSSTUDENTSSURVEYFORR contains the column ENDBREATHMIN (a numerical variable that measures post-survey student breaths per minute) and the column UNDERGORGRAD (a categorical variable that measures whether the student is planning a GraduateProfessional or an Undergraduate degree). For education purposes, assume that the two groups are two independent samples from a much larger normal population for statistics students. Use the appropriate test to test, at the 5% significance level, whether, on average, the post-survey breaths per minute differs for the GraduateProfessional and Undergraduate groups. Use the difference uGraduateProfessional - Undergraduate. Which of the following statements is most correct? O Your test statistics is -0.1731 and you fail to reject your Ho. O Your test statistic is -0.1731 and you reject your Ho. O Your test statistic is 0.1731 and your fail to reject your Ho. O Your test statistic is 0.1731 and you reject your Ho. 1 points
