A study analyzed the sustainability behaviors of CPA corporations. The level of support for corporate sustainability (measured on a quantitative scale ranging from 0 to 160 points) was obtained for each in a sample of 982 senior managers at CPA firms. The CEO of a CPA firm claims that the true mean level of support for sustainability is 75. Complete parts a through e below. iClick the icon to view a printout of the analysis. Vy OB. A Type Il error would be to conclude that the true mean level of support for sustainability is not 75 when, in fact, the mean is equal to 75. OC.

Locate the p-value on the printout. p-value = (Type integers or decimals.) d. At a = 0.05, give the appropriate conclusion. OA. Reject the null hypothesis that the true mean level of support for sustainability is 75 because the p-value is greater than the level of significance a = 0.05. OB.

No assumptions are necessary because the sample size is very large. B. One must assume that the distribution of support levels is normal because the population standard deviation is not give. C. One must assume that the distribution of support levels is symmetric because the test is two-tailed. D. One must assume that the distribution of support levels is normal because the sample size is very large.
