Your insurance company has converged for three types of cars. The annual cost for each type of cars can be modeled using Gaussian (Normal) distribution, with the following parameters: (Discussions allowed!)

  • Car type 1 Mean=$520 and Standard Deviation=$110

  • Car type 2 Mean=$720 and Standard Deviation=$170

  • Car type 3 Mean=$470 and Standard Deviation=$80

Use Random number generator and simulate 1000 long columns, for each of the three cases. Example: for the Car type 1, use Number of variables=1, Number of random numbers=1000, Distribution=Normal, Mean=520 and Standard deviation=110, and leave random Seed empty.

Next: use either sorting to construct the appropriate histogram or rule of thumb to answer the questions:

13. What is approximate probability that Car Type 3 has annual cost less than $550?

  • a. Between 1% and 3%

  • b. Between 27% and 39%

  • c. Between 75% and 90%

  • d. None of these

14. Which of the three types of cars is most likely to cost less than $400?

  • a. Type 1

  • b. Type 2

  • c. Type 3

15. For which of the three types we have the highest probability that it will cost between $500 and $700?

  • a. Type 1

  • b. Type 2

  • c. Type 3

What is the test statistic?

What are the degrees of freedom?

What is the P-value? (Round to 3 decimal places). How do you find the p value?

Based on the results of this test, is there enough evidence to say that the mean salary of NBA players increased from 1996 to 2006? Use a level of significance of α=0.05.

The following data were obtained in a study using three separate samples to compare three different treatments. Conduct an analysis of variance with α=0.05α=0.05 to determine whether these data are sufficient to conclude that there are significant differences between the treatments.

Conclusion:

  • There is a significant difference between treatments
  • These data do not provide evidence of a difference between the treatments

The above data was changed by increasing the variance within each sample (note below how the data sets have changed).

Before you begin the calculation, predict how the changes in the data should influence the outcome of the analysis. That is, how will the F-ratio for these data compare with the F-ratio from above?

There are many situations that may contribute to the inflation of an economy where the volatility and uncertainty can lead to lower levels of investments. With regards to the current situation that is taking place around the world (COVID-19), many stores and businesses in the Kingdom of Bahrain and around the world were faced to close their doors to customers for at least two weeks. Explain in your own words, how these businesses and financial institutions will make up for the losses they are or may face. Will these businesses and financial institutions cause inflation within the economy? Explain.

Write a C# program that prints a calendar for a given year. Call this program calendar. The program prompts the user for two inputs:
      1) The year for which you are generating the calendar.
      2) The day of the week that January first is on, you will use the following notation to set the day of the week:
    
      0 Sunday                     1 Monday                   2 Tuesday                   3 Wednesday
      4 Thursday                 5 Friday                      6 Saturday

Your program should generate a calendar similar to the one shown in the example output below. The calendar should be printed on the screen. Your program should be able to handle leap years. A leap year is a year in which we have 366 days. That extra day comes at the end of February. Thus, a leap year has 366 days with 29 days in February. A century year is a leap year if it is divisible by 400. Other years divisible by 4 but not by 100 are also leap years.

Example: Year 2000 is a leap year because it is divisible by 400.  Year 2004 is a leap year because it is divisible by 4 but not by 100.
Your program should clearly describe the functionality of each function and should display the instructions on how to run the program.

Your need to create one method “displayMonth” for print each month as required. You can choose return method or not that depend on your design.

Sample Input:

Enter the year for which you wish to generate the calendar: 2004
Enter the day of the week that January first is on: 4

Sample output:
