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. a. Specify the null and alternative hypotheses for testing this claim. A. H0: μ=66 Ha: μ<66 B. H0: μ≠66 Ha: μ=66 C. H0: μ=66 Ha: μ>66 D. H0: μ=66 Ha: μ≠
The toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases. Here are data for beak heat loss, as a percent of total body heat loss from all sources, at various temperatures in degrees Celsius. [Note: The numerical values in this problem have been modified for testing purposes.] Temperature (oC)(oC) 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 Percent heat loss from beak 33 32 33 32 39 43 56 48 44 49 44 56 58 60 60 63 The equation of the least-squares regression line for predicting beak heat loss, as a percent of total body heat loss from all sources, from temperature is: (Use decimal notation.

A 1992 article in the Journal of the American Medical Association ("A Critical Appraisal of 98.6 Degrees F, the Upper Limit of the Normal Body temperature, and Other Legacies of Carl Reinhold August Wundrlich") reported body temperature, gender, and heart rate for a number of subjects. The temperatures for 25 female subjects follow: 98.397.297.497.6 97.8 97.9 98.0 98.0 98.2 98.1 98.2 98.3 98.3 98.498.498.498.5 98.6 98.6 98.7 98.8 98.8 98.9 98.9 99.0 With hypothesis HO: µ = 98.6 versus H1 : µ + 98.6, using a = 0.05, determine the test statistic t0 and draw conclusion.

The average starting salary of students who graduated from colleges of Business in 2009 was $48,400.A sample of 100 graduates in 2010 showed an average starting salary of $50,000. Assume the standarddeviation of the population is known to be $8000. We want to determine whether or not there hasbeen a significant increase in the starting salaries.Step 1. Statement of the hypothesis Step 2. Standardized test statistic formula Step 3. State the level of significance Step 4. Decision Rule (Draw a bell to show rejection zone) Step 5. Calculation of the statistic Step 6. Conclusion

A statistical program is recommended. Electric power consumption is measured in kilowatt-hours (kWh). The local utility company offers an interrupt program whereby commercial customers that participate receive favorable rates but must agree to cut back consumption if the utility requests them to do so. A certain company cuts back consumption at 12:00 noon Thursday. To assess the savings, the utility must estimate the company's usage without the interrupt. The period of interrupted service was from noon to 8:00 p.m. Data on electric power consumption for the previous 72 hours are available.
