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 984 senior managers at CPA firms. The CEO of a CPA firm claims that
the true mean level of support for sustainability is 66. Complete parts a through e.

mean is greater than 66.
OC. A Type Il error would be to conclude that the true mean level of support for sustainability is not 66 when, in fact, the mean is equal to
66.
OD. A Type Il error would be to conclude that the sample mean level of support for sustainability is greater 66 when, in fact, the sample
mean is less 66.

Follow-up Question

d. At α=0.05,give the appropriate conclusion. Choose the correct answer below.

A. Reject the null hypothesis. There isinsufficientevidence at the α=0.05 level of significance to conclude that the true mean level of support for sustainability is equal

66.

B.Do not reject the null hypothesis. There is sufficientevidence at the α=0.05level of significance to conclude that the true mean level of support for sustainability is not equal to 66.

C.Reject the null hypothesis. There is sufficientevidence at the α=0.05level of significance to conclude that the true mean level of support for sustainability is not equal to 66.

D. Do not reject the null hypothesis. There is sufficientevidence at the

α=0.05 level of significance to conclude that the true mean level of support for sustainability is greater than 66.
