A manufacturer is interested in the output voltage of a power supply used in a PC. Output voltage is assumed to be normally distributed, with standard deviation 0.91 volt, and the manufacturer wishes to test $H_0: \mu = 5$ volts against $H_1: \mu \neq 5$ volts, using $n = 7$ units. In your intermediate calculations, use z-scores rounded to two decimal places (e.g. 98.76). Round your answers to four decimal places (e.g. 98.7654). (a) The acceptance region is $4.88 \leq \bar{x} \leq 5.13$. Find the value of $\alpha$. (b) Find the power of the test for detecting a true mean output voltage of 5.1 volts.

Current Attempt in Progress A very long, straight wire carries a current of 0.14 A. This wire is tangent to a single-turn, circular wire loop that also carries a current. The directions of the currents are such that the net magnetic field at the center of the loop is zero. Both wires are insulated and have diameters that can be neglected. How much current is there in the loop? $I_{loop}$ =

case made 24,500 units during June, using 32,000 direct labor hours. They expected to use 31,450 hours per the standard cost card. Their employees were paid $15.75 per hour for the month of June. The standard cost card uses $15.50 as the standard hourly rate. A. Compute the direct labor rate and time variances for the month of June, and also calculate the total direct labor variance. B. If the standard rate per hour was $16.00, what would change?

Tiffany's makes earrings. The total cost to make 1,000,000 earrings are as follows: Material: $160,000 Labor: $60,000 Indirect costs: Variable: $120,000 Fixed: $170,000 Total Cost: $510,000 Zales has offered to make the earrings for $0.40. If Tiffany purchases the earrings from Zales, 40% of the fixed costs will be avoided. The remaining 60% will continue regardless of whether the earrings are manufactured or purchased. If the earrings are purchased, the capacity currently used to make the earrings will be idle. In turn, the idle capacity can be leased out resulting in an additional contribution of $50,000 with a related maintenance cost to Tiffany's of $20,000. How much would Tiffany's save or lose by buying the earrings from Zales? MAKE or BUY
