A battery manufacturer tests its newly developed EV battery by constructing a mean chart for controlling the service life of a fully charged battery. The company knows from previous samples that when the service life is in control it is normally distributed with a mean of 500 hours and a standard deviation of 10 hours. On three recent production batches, the firm tested service life on random samples of four batteries, with these results: Sample Service Life (hours) 1 495 500 505 500 2 525 515 505 515 3 494 485 506 499 What is the mean of the sampling distribution of sample means when the service life is in control? 500 What is the sample mean service life for sample 3? 496 What is the standard deviation of the sampling distribution of sample means for whenever service life is in control? 5 If he uses upper and lower control limits of 505 and 495 hours, what is his risk (alpha) of concluding that service life is out of control when it is actually under control (Type I error Normal table.pdf )? 1 (Provide your answer in 0.**** format) If he uses upper and lower control limits of 505 and 495 hours, on what sample(s) (if any) does service life appear to be out of control?

A panel of three high school teachers at Rippowam High School had been convened by the principal to make a most important decision. A local company was willing to award a $10,000 college scholarship to "the most outstanding senior" in the class, with the recipient to be determined by the high school. Walter Plant, Sandra Meltzer, and Jerry Driscoll were given the assignment to select the scholarship recipient. They agreed to meet at 2:30 to discuss their assignment. Driscoll opened the meeting: "I wish we had more to go on than what they gave us. A student can be 'outstanding' in many ways." "Well, I assume grades are the most important factor," said Meltzer. "Why don't we start out with the ranking of all students based upon their grade-point averages. I'd be hard pressed to award $10,000 to any student other than the class valedictorian." "I don't think it’s that easy," continued Plant. "I am far more impressed with a student who gets a B+ in honors physics than someone who gets an A in basketweaving. While a student's grade point average is certainly a good measure of their academic accomplishments, it's tainted by the difficulty of the courses taken." "That's not the only problem with the grade point average," Driscoll warned. "I've got some students in my homeroom who will graduate with the minimum number of hours, and I've got some others who branched out and took more than the minimum. I think we should give some consideration to the total number of hours taken in the curriculum." A deep frown appeared on Plant's face. "I don't see why we should penalize the student who did only what was required by the school. We specify what is needed for graduation, and the students have to comply. While I never encourage a student to stick to the minimum, I don't think we should devalue their performance for having done so." "Maybe we're getting too hung up with grades and hours," said Meltzer. “Suzanne Millord won first prize in the regional science fair competition. Shouldn't something like that count too? I'm more impressed with that than an A in any class." "You know," Plant commented, "we are forgetting about some other things too. How about civic activities, such as participation in student government or interest clubs? We encourage student involvement in these activities to make for a more well-rounded education. I don't feel we should ignore them when it comes time to make an award." "I feel those activities have their own rewards," said Driscoll. "We want to give this scholarship to the best student, not the most socially active one." "While we're at it," mused Plant, "how about athletic participation? We also stress physical education as well as social and intellectual development. Maybe we should also include interscholastic athletics. We've got some outstanding athletes in this school, and who’s to say that 'most outstanding' can't be defined in terms of athletics?" "I hardly think this was designed to be an athletic scholarship," Meltzer grumbled. "If you want to make it more complicated, why not throw in financial need; $10,000 is a lot of money, and some families could use it more than others." Driscoll stared out the window. He knew it would be a long afternoon
Would the criteria for selecting the "most outstanding student" be more biased or less biased by the inclusion of financial need? Why?

CSCI 3000 Homework 5
In this homework, you will manage the car data of a dealer. First, you will design a C++ class called Car. A single Car variable (object) have five member variables (attributes): VIN, make, model, year, and price.
Car class attributes should be private, and set/get functions should be implemented to access and update the values. Also, you should have at least two constructor functions to initialize Car objects. Finally a print() function should be implemented to print single Car data on the screen.
Class description is given below:

Once your class is ready, you will read the “cardata.txt” file, which includes all 250 cars in the dealer. A sample view of the file is given below:
…
Before you read file, you will create an array of cars having size of 250. This number is always 250 and does not change. In the file, each line contains a single car, for which attributes are separated by space character. So, you can read one line using a simple while loop such as:
While(inputFile >> VIN >> make >> model >> year >> price){
//create new car and send it to the corresponding array index
...
}
Once your car array is ready, you will provide following operations to the user in a menu.
You can write your code (including the car class definition and main function) in a single cpp file and submit that file. If you can separate the class files from the main program, you will get extra 10 points for the assignment. In that case, you will need to submit three files such as, “car.h”, “car.cpp”, and “main.cpp”. I will show you how to separate class files from main program in class.
On the top of your source code, please add your name and number, Course ID, HW number and the date using a comment block. Please see the example below,

Grandma decides to put 1200 dollars every month into an account for you. She makes 16 monthly deposits, the last coming September 1, 2019 - the day you start college. She wants you to be able to withdraw money from this account at the beginning of each month, with the first withdrawal coming September 1, 2019 and the last coming June 1, 2024, (when you'll graduate). (Note: that makes 58 withdrawals total.) How much will you be able to withdraw each month if the account is earning a nominal interest rate of 7.5 percent convertible monthly?

During 2019, Brent Industries, Inc. constructed a new manufacturing facility at a cost of $12,000,000. The weighted average accumulated expenditures for 2019 were calculated to be $5,750,000. The company had the following debt outstanding at December 31, 2019:
(a) 7 percent, five-year note to finance construction of the manufacturing facility, dated January 1, 2019, $4,000,000.
(b) 9 percent, 20-year bonds issued at par on April 30, 2015, $8,400,000.
(c) 7 percent, six-year note payable, dated March 1, 2017, $1,800,000.
Required:
1. Determine the amount of interest that should be capitalized in 2019 assuming that the facility is completed at the end of 2019. DON'T NEED
2. Show the most likely journal entry to record the capitalized interest assuming that Brent recorded all interest as expense when paid or accrued. DON'T NEED
3. Give the journal entry to record depreciation on the facility in 2020 assuming a 25 year useful life and no salvage value.
4. Give the journal entry to sell the manufacturing facility at the end of 2030 for $7 million in cash.

Q:
You must evaluate a proposal to buy a new milling machine. The base price is $138,000, and shipping and installation costs would add another $13,000. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $62,100. The applicable depreciation rates are 33%, 45%, 15%, and 7%. The machine would require a $9,500 increase in net operating working capital (increased inventory less increased accounts payable). There would be no effect on revenues, but pretax labor costs would decline by $47,000 per year. The marginal tax rate is 35%, and the WACC is 11%. Also, the firm spent $5,000 last year investigating the feasibility of using the machine.
