Ted Olson, director of the company Overnight Delivery, is worried because of the number of letters of first class that his company has lost. These letters are transported in airplanes and trucks, due to that, mister Olson has classified the lost letters during the last two years according to the transport in which the letters were lost. The data is as follows:
|

Mister Olson will investigate only one department, either aerial o ground department, but not both. He will open the investigation in the department which has the most number of lost letters per month, find:
23.- The expectation value of lost letters per month in truck.
24.- The expectation value of lost letters per month in airplane.

Maglie Company manufactures two video game consoles: handheld and home. The handheld consoles are smaller and less expensive than the home consoles. The company only recently began producing the home model. Since the introduction of the new product, profits have been steadily declining. Management believes that the accounting system is not accurately allocating costs to products, particularly because sales of the new product have been increasing.
Management has asked you to investigate the cost allocation problem. You find that manufacturing overhead is currently assigned to products based on their direct labor costs. For your investigation, you have data from last year. Manufacturing overhead was $1,209,000 based on production of 320,000 handheld consoles and 85,000 home consoles. Direct labor and direct materials costs were as follows:
| Handheld | Home | Total | |||||||
| Direct labor | $ | 1,099,250 | $ | 412,000 | $ | 1,511,250 | |||
| Materials | 710,000 | 685,000 | 1,395,000 | ||||||
Management has determined that overhead costs are caused by three cost drivers. These drivers and their costs for last year are as follows:
| Activity Level | ||||||
| Cost Driver | Costs Assigned | Handheld | Home | Total | ||
| Number of production runs | $ | 500,000 | 35 | 15 | 50 | |
| Quality tests performed | 540,000 | 10 | 20 | 30 | ||
| Shipping orders processed | 169,000 | 80 | 50 | 130 | ||
| Total overhead | $ | 1,209,000 | ||||
Required:
a. How much overhead will be assigned to each product if these three cost drivers are used to allocate overhead? What is the total cost per unit produced for each product? (Round "Total cost per unit" to 2 decimal places.)
b. How much overhead will be assigned to each product if direct labor cost is used to allocate overhead? What is the total cost per unit produced for each product? (Do not round intermediate calculations. Round "Total cost per unit" to 2 decimal places.)

If you hear that unemployment increased in the last year by 3.5 percentage points to 8 %it means: Multiple Choice 80 out of every 100 people who want a job can't find one. 35 out of every 100 people lost their job in the last year. 35 out of every 1,000 people lost their job in the last year. 8 out of every 1,000 people who want a job can't find one.

Watch a basketball, baseball, or football game. For the baseball, monitor and innings pitches for balls and strikes (all foul balls in play count as strikes). For football monitor a series of plays for runs versus passing plays. For basketball monitor one teams shots for misses versus made shots. For the collected data, conduct a runs test to see if the distribution is random.

Design a state machine, using the D flip-flop, that implements a
00 and 11 sequence detector. Your machine should output a
1 as soon as it detects two 0s or
two 1s on its input, otherwise it outputs
0s.
Write a module that implements the machine and a test bench to test
it.

Jeremy is a 25-year-old man training for an ultramarathon race of 50 miles. He is 5 feet, 10 inches tall and currently weighs 170 lb. During his long runs of more than 3 hours, he drinks water, approximately 30 oz., and consumes one GU (an energy supplement containing 100 kcal from simple sugar) at the 2-hour mark. Jeremy is coming to you for advice because he is becoming increasingly weak and nauseated toward the end of his runs. He reports feeling light-headed and irritable on his long training days. Jeremy states that he is eating an egg salad sandwich with two hard-boiled eggs mixed with 3 tbsp. of mayonnaise on whole wheat bread about 20 minutes before his run.

A study of reading comprehension in children compared three methods of instruction. The three methods of instruction are called Basal, DRTA, and Strategies. Basal is the traditional method of teaching, while DRTA and Strategies are two innovative methods based on similar theoretical considerations. The READING data set includes three response variables that the new methods were designed to improve. Analyze these variables using ANOVA methods. Be sure to include multiple comparisons or contrasts as needed. Write a report summarizing your findings.
