In addition to tests involving biology concepts, students were also tested on process skills. The results of pretest and posttest scores, published in The American Biology Teacher, are given below.

Pretest: All BACC Classes: Mean 10.52, Sample Size 395, Standard Deviation 4.79 Pretest: All Traditional: Mean 11.97, Sample Size 379 and Standard Deviation 5.39 Posttest: All BACC Classes: Mean 14.06, Sample Size 376, Standard Deviation 5.65 Posttest: All Traditional: Mean 12.96, Sample Size 308, Standard Deviation 5.93

a. Find a 95% confidence interval for the mean score on process skills for the posttest for all BACC classes. b. Find a 95% confidence interval for the mean score on process skills for the posttest for all traditional classes. c. Find a 95% confidence interval for the difference in mean scores on process skills for the posttest BACC classes and the posttest traditional classes. d. Does the confidence interval in c provide evidence that there is a real difference in the mean process skills scores between posttest BACC and traditional class scores? Explain.

Ceiling fans use electric motors that involve stationary permanent magnets (called stators) attached to the central hub and with a typical strength of 1.0 T, that supply torque to current-carrying coils (called rotors) fixed to the fan blades. Think of a ceiling fan at your home or workplace.

Estimate the diameter of the central hub at the inner edge of the blades.

On July 1, 2012, Hallo Corporation, a wholesaler of communication equipment, issued $34,000,000 of 20-year, 12% bonds at a market (effective) interest rate of 13%, receiving cash of$31,595,241. Interest on the bonds is payable semiannually on December 31 and June 30. The fiscal year of the company is the calendar year.

Instructions

1. Journalize the entry to record the amount of cash proceeds from the sale of the bonds.
2. Journalize the entries to record the following: a. The first semiannual interest payment on December 31, 2012, and the amortization of the bond discount, using the interest method. (Round to the nearest dollar.) b. The interest payment on June 30, 2013, and the amortization of the bond discount, using the interest method. (Round to the nearest dollar.)
3. Determine the total interest expense for 2012.

Structural unemployment is sometimes said to result from a mismatch between the job skills that employers want and the job skills that workers have. To explore this idea, consider an economy with two industries: auto manufacturing and aircraft manufacturing.

Suppose that workers in one industry cannot be quickly retrained for the other. How would these shifts in demand affect equilibrium wages both in the short run and in the long run?

What precautions can humans take to avoid the dangers associated with mass movements?
