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. What is a Type II error in this problem? A. A Type II error would be to conclude that the true mean level of support for sustainability is 66 when, in fact, the mean is not equal to 66. B. A Type II error would be to conclude that the sample mean level of support for sustainability is less than 66 when, in fact, the sample mean is greater than 66. C. A Type II 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. D.
