A study analyzed the sustainabilly behaviors of CPA corporations The Suvel of support for corporate sustainability (measured on a quantitative scale ranging from 0 to 10 points) was ined for eachina sample of 976 senior managers at CPA firms The CEO of a CPA fim daim that the true mean level of support for sustainability is 73. Complete parts a throughe Click the icon to view the printout, a. Specify the null and alternative hypotheses for testing this daim OA -- HT loc. Ho p=73 Ов, но и H = 7 OD H7 H> 73 s. For this problem, what is a Type letor? A Typell error? What is a Type error in this problem? OA A Type 1 error would be to conclude that the sample mean level of support for sustainabilly be greater than 73 when, in fad, the sample is less than 08. A Type error would be to conclude that the true mean level of support for sustawy ?) when in fact, the man is not equal to 73. OG A Type error would be to conclude that the true mean level of support for sustainability is not 73 when in fact, the mean equal to 73 OD. A Type or would be la conclude that the sample mean level of support for sustainability is less than a when, in fact, the sample mean is greater than 73 What is a Type Il error in thin problem? DA A Type Honor would be to conclude that the sample mean level of support for sustainability is less than 73 when. In fact, the sample mean in greater than 73 OB. A Typefl error would be to conclude that the mean level of support for sustainability is not 73 when in fact, the mean I equal to 73 OC. A Type Ierror would be to conclude that the sample mean level of support for sustainability is greater 73 when, in fact, the sample maan is less 73 OD. A Type llenor would be to conclude that the true mean level of support for sustainability is 73 when, in fact the mean is not equal to 73 The provided printout of the analysis gives the results of the test. Locate the test statistic and the p value on the printout est statistic value Type integers or decimals. Do not found Ala005 give the appropriate conclusion Choose the correct answer below
d. Ala-005, give the appropriate conclusion Choose the correct answer below O A. Do not reject the null hypothesis There is sufficient evidence at the 0.05 level of significance to conclude that the true mean level of support for sustainability is greater than 73 OB. Reject the null hypothesis. There is insufficient evidence at the -0.05 level of significance to conclude that the true mean level of support for sustainability is equal 73 OC. Reject the null hypothesis. There is sufficient evidence at the a-005 level of significance to conclude that the true mean level of support for sustainability is not equal to 73 OD. Do not reject the rull hypothesis. There is sufficient evidence at the a 0,05 level of significance to conclude that the true mean level of support for sustainability is not equal to 13. e. What assumptions, Wany about the distribution of support levels must hold true in order for the interence derived from the best to be vald? Explain. Select all that apply CA One must assume that the distribution of support levels asymmetric because the test is two tailed DB One must assume that the distribution of support levels is normal because the sample site is very large DC One must assume that the distribution of support levels is normal because the population standard deviation is not given OD. No assumptions are necessary because the sample size is very large
