A manufacturing company produces steel housings for electrical equipment. The main component part of the housing is a steel trough that is made out of a 14-gauge steel coil. It is produced using a 250-ton progressive punch press with a wipe-down operation that puts two 90-degree forms in the flat steel to make the trough. The distance from one side of the form to the other is critical because of weatherproofing in outdoor applications. The company requires that the width of the trough be between 8.31 inches and 8.61 inches.

The data below represents the widths of the troughs, in inches, for a sample of n = 49:

8.312 8.343   8.317   8.383 8.348   8.410   8.351 8.373   8.481   8.422

8.476 8.382   8.484   8.403 8.414   8.419   8.385 8.465   8.498   8.447

8.436   8.413   8.489 8.414   8.481   8.415 8.479   8.429   8.458 8.462

8.460 8.444   8.429   8.460 8.412   8.420 8.410 8.405   8.323   8.420

8.396 8.447   8.405   8.439 8.411   8.427   8.420 8.498   8.409

(a) At the 0.05 level of significance, is there evidence that the mean width of the troughs is different from 8.46 inches? Be sure to include the following in your answer:

i.                     List the null and alternate hypotheses

ii.                   Find the value of the test statistic

iii.                 List the decision rule.

iv.                 Conclude in a complete sentence and include why you decided as you did – referring to the decision rule.

(b) What assumption about the population distribution is needed in order to conduct the t test in (a)?

Melcom announced April 19, 2015 as National Hiring Day in Ghana. Melcom has 1000 shopping outlets
across the country and has 20000 employees. On April 19, this figure will be 60000 employees i.e. roughly
40 workers per each shopping Centre.
As per the plan, Melcom will hire 40,000 new employees in various part-time and full-time positions at
crew and management levels. The starting wage will typically be more than Ghc50.00 per day. Outlet
managers can earn up to Ghc30,000.00 a year. Melcom was also recently selected by the Agoo Magazine
as one of the best companies in the country for internship and part-time jobs.
Around 75% of outlet managers and 40% of corporate employees at Melcom started as attendants and
cleaners at both part-time and full-time basis. This should be great news for those who see it as a first step
to a better career later, either within or outside the company. This should also be good news for the
Ghanaian economy where the national unemployment rate is around 6.7 percent.
Melcom country held a meeting with the HR management of the company and held a press conference
where among many other things he urged prospective applicants to take advantage of the opportunity as
the company intends to diversify its recruitment process. The biggest hiring initiative in company history
comes in the wake of growing number of 24-hour stores across the country.
REQUIREMENTS
As the head of the HR management, you are required to plan the recruitment process through a 3-month
timeline.

1. Murphy’s Law, a pub in downtown Rochester, claims its patrons average 25 years of age. A random sample of 40 bar patrons is taken and their mean age is found to be 26.6 years with a standard deviation of 4.5 years. Do we have enough evidence to conclude at the level of significance α = 0.025 that, on average, patrons at Murphy’s Law are older than 25?

Determine the test statistic.

Determine the range of P-values.

Write your decision and explain how you reached it.

Write the conclusion that addresses the original claim.

Determine the type of error you could have made and explain why. (Type I or Type II

error)

2. The coffee machine at your company has been acting weirdly these past few days. You were assured that the machine would pour 7 ounces of coffee every time you press the button. You believe that this is not true anymore and want to call the technician. Before you do so, you gather a sample of 15 coffees and find out that the mean amount of coffee in each cup is 6.8 ounces with a standard deviation of 1 ounce. Is there sufficient evidence to show that the population mean is different than 7 ounces? Perform a test at the 0.05 level of significance. Assume normality.

Determine the test statistic.

Determine the range of P-values.

Write your decision and explain how you reached it.

C#:

A book publisher has limited the cost of every book they publish to no more than 10 cents per page.

1. Create a BookException class with a constructor that requires three (3) arguments for each book: a string title, a double price and an int number of pages.

2. Create an error message that is passed to the Exception class constructor for the Message property when a book does not meet the price-to-pages ratio. The error message might be:

                                                                        For Goodnight Moon, ratio is invalid.

                                                                        ...Price is $12.99 for 25 pages

   The price-to-pages ratio is determined by checking the following:  price > RATE * pages where RATE = 0.10

3. Create a Book class that has the following fields:  string title, string author, double price and int number of pages.

4. Create properties (accessors) for each field.

5. Throw a BookException if a book object is created that has a price that is more than 10 cents per page.

6. In Main create 4 Book objects and use the constructor for Book to pass the four inputs when each object is instantiated, some where the ratio is correct and some where the ratio is not correct.

7. Catch any thrown exceptions and display BookException Message.

8. Internal Documentation.

9. Possible output:

       The inputs passed were:

               ("Goodnight Moon", "Brown", 12.99, 25)

               ("World History", "Stein", 72.99, 900)

               ("The Grapes of Math", "Stoltz", 30.99, 300)

               ("Steal This Book", "Hoffman", 72.99, 800)

       The results were:

   For Goodnight Moon, ratio is invalid.
   ...Price is $12.99 for 25 pages.
   For The Grapes of Math, ratio is invalid.
   ...Price is $30.99 for 300 pages.

Write a Java program in Eclipse to calculate the total cost to enter into a waterpark for a family/group

Ticket rates are listed below

kids (Age 12 and under)=$ 12.50

Regular( Age between12 -55) =$ 18.25

Seniors (55 and above) = $15.00

Tax =7%

Your program should ask the user to enter the total number of members in their group.

User needs to enter the ages for all members. Write appropriate error messages for invalid entries.

An array should be used to store the ages of the family members.

Based on the age it has to calculate the cost of each member and calculate the total cost including tax.

Your program should display

The number of tickets for each type

And the total cost for the group

After display your program should repeat the process until the user wants to stop.

Your program must use

1. Array
2. Do while Loop
3. Constant variable
4. Atleast one method

Sample run of the program:

Snakes and ladders is an ancient south Asian board game. It consists of 10X10 grid board which
contains some snakes and ladders at specific boxes/indexes. One hundred is the maximum and a must
to win score for each player. First player reaching 100 gets to win the game and is immediately
declared as first Winner.
You are required to do the following:
 Create a snake board of 10 rows and 10 columns.
 Randomly generate 09 snakes on the board. In order to generate snake you only need to know
head and tail of the snake. Make sure that both head and tail are on the board. Moreover, if
head is on row (Mi) and tail is on row (Mj) then i will always be less than j.
 Similarly, generate 09 ladders on the board.
 Print the snake board along with snakes and ladders on the screen.
 In order to start both the player need a six on the dice. Once the game is started display the
output on the dice and wait for key press (you can use getch()) before second player’s turn.
 Game will go on until one player wins the game.
 In case player lands on a snake’s head it will come down to its tail, here you need to display a
message “oops, snake got you!!!”
 In case player lands on the bottom of the leader it will climb the ladder, here you need to
display a message “you got lucky”
Note: Input validation is mandatory when reading taking input size of the board.
