(Science: day of the week)

Zeller’s congruence is an algorithm developed by Christian Zeller to calculate the day of the week.
The formula is :

h = (q + 26(m+1)/10 + k + k/4 + j/4 + 5j) % 7

where

- h is the day of the week (0: Saturday, 1: Sunday, 2: Monday, 3: Tuesday, 4: Wednesday, 5: Thursday, 6: Friday).

- q is the day of the month.

- m is the month (3: March, 4: April, ..., 12: December). January and February are counted as months 13 and 14 of the previous year.

- j is the century (i.e., year/100)

- k is the year of the century (i.e., year%100).

Note that the division in the formula performs an integer division.

Write a program that prompts the user to enter a year, month, and day of the month, and displays the name of the day of the week.

Sample Run 1

Enter year: (e.g., 2012): 2015
Enter month: 1-12: 1
Enter the day of the month: 1-31: 25
Day of the week is Sunday

Sample Run 2

Enter year: (e.g., 2012): 2012
Enter month: 1-12: 5
Enter the day of the month: 1-31: 12
Day of the week is Saturday

Sample Run 3

Enter year: (e.g., 2012): 2002
Enter month: 1-12: 3
Enter the day of the month: 1-31: 26
Day of the week is Tuesday

Sample Run 4

Enter year: (e.g., 2012): 2008
Enter month: 1-12: 1
Enter the day of the month: 1-31: 1
Day of the week is Tuesday

Sample Run 5

Enter year: (e.g., 2012): 2000
Enter month: 1-12: 2
Enter the day of the month: 1-31: 12
Day of the week is Saturday

(Hint: January and February are counted as 13 and 14 in the formula, so you need to convert the user input 1 to 13 and 2 to 14 for the month and change the year to the previous year.)

The following algorithm is widely used for checking whether a credit or debit card number has been entered correctly on a website. It doesn't guarantee that the credit card number belongs to a valid card, but it rules out numbers which are definitely not valid. Here are the steps:

1. Check that the long number has exactly 16 digits. If not, the long number is not valid.
2. If the long number has 16 digits, drop the last digit from the long number, as this is the "check digit" that we want to check against.  
3. Multiply by 2 the value of each digit starting from index 0 and then at each even index. In each case, if the resulting value is greater than 9, subtract 9 from it. Leave the values of the digits at the odd indexes unchanged.
4. Add all the new values derived from the even indexes to the values at the odd indexes and call this S.
5. Find the number that you would have to add to S to round it up to the next highest multiple of 10. Call this C. If C equals the check digit, then the long number could be valid.

Example

Here is a worked example using the long number "4916592478445662".

1. There are exactly 16 digits.
2. So, create a new string including the first fifteen digits of the long number, i.e. "491659247844566" and note that the dropped digit, 2, is the check digit.
3. Multiply by 2 the value of each remaining digit starting from index 0 and then each even index. In each case, if the resulting value is greater than 9, subtract 9 from it (which reduces larger values to a single digit). Leave the values of the digits at the odd indexes unchanged.

4. Find S by adding all the values in the last column:

   S = 8 + 9 + 2 + 6 + 1 + 9 + 4 + 4 + 5 + 8 + 8 + 4 + 1 + 6 + 3 = 78

5. As S = 78, the next highest multiple of 10 is 80. To get from 78 to 80 you must add 2, so C = 2. As this equals the value of the last digit in the long number, the long number could be valid.

a- Write a public method called isCorrectLength() that takes no arguments and returns the boolean value true if the length of longNumber is 16 and false otherwise.

b - Write a public method firstFifteen() that returns a String consisting of the first fifteen characters in the longNumber.

c) - write a public method calculateCheckNumber() to find S and then use the expression S/10 * 10 + 10 – S to find C. The method should first create a string omitting the last digit of the longNumber and then find S by iterating through this string. (You may choose to do a separate iteration for the odd and even indexes, or you could do both in a single loop.)

The Tri-City Office Equipment Corporation sells an imported copier on a franchise basis andperforms preventive maintenance and repair service on this copier. The data below have beencollected from 45 recent calls on users to perform routine preventive maintenance service; foreach call, X is the number of copiers serviced and Y is the total number of minutes spent bythe service person. Assume that first-order regression model (1.1) is appropriate CH01PR20.txt (a) Estimate the change in the mean service time when the number of copiers serviced increases by one. Use a 90 percent confidence interval. Interpret your confidence interval. (d) The manufacturer has suggested that the mean required time should not increase by more than 14 minutes for each additional copier that is serviced on a service call. Conduct a test to decide whether this standard is being satisfied by Tri-City. Control the risk of a Type I error at 0.05. State the alternatives, decision rule, and conclusion. What is the P-value of the test? (e) Does b subscript 0 give any relevant information here about the ``start-up" time on calls, that is, about the time required before service work is begun on the copiers at a customer location?

In this experiment, all participants rated the credibility of fake news stories on a scale of 1 to 10, with higher numbers indicating greater belief. Subjects made ratings after writing a control essay about doing something successfully, and also after writing an essay about an incident in which they were bullied, rejected or otherwise socially excluded (the treatment condition).

1. In conceptual terms, the hypothesis is that social exclusion increases belief in fake news. State this hypothesis in statistical terms and include the correct notation. [1 point]

2. Explain why the t test for dependent (paired) samples is the appropriate test for the hypothesis in terms of the formula for t. [1 point]

3. Compute the means, standard deviations. [1 point]

4. Compute and interpret the effect size (d) for the differences between means. [2 points]

5. Summarize the results of the t test. Also include the correct notation. Are the results of the test significant, i.e., likely in the population? Why or why not? Should you reject or retain the null hypothesis? [4 points]

6. Summarize the results in terms of the conceptual hypothesis and variables. Explain why you think the results have practical meaning (or not). Refer to both t and d in your answer. [1 point]
