a. Specify the null and alternative hypotheses for testing this claim. b. For this​ problem, what is a Type I​ error? A Type II​ error? c. The observed significance​ level, or​ p-value, for a specific statistical test is the probability​ (assuming μ0 is​ true) of observing a value of the test statistic that is at least as contradictory to the null hypothesis, and supportive of the alternative​ hypothesis, as the actual one computed from the sample data. Locate the​ p-value on the printout.

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 974 senior managers at CPA firms. The CEO of a CPA firm claims that the true mean level of support for sustainability is 71. Complete parts a through e below. ✪ Click the icon to view a printout of the analysis. a.
