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

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.

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?

Given the following data on the Dollar/Pound exchange rate (y) and the U.S. CPI (x), determine the linear regression equation, and include the Summary Output from Excel. • Based on the Summary Output is the coefficient b2 significant using the t-table (one-tail) at the 5% level with n-2 df? Prove your answer using data from the t-table. • Does the relationship given by the regression equation seem to be a reasonable economic model-- is it reasonable to assume that in this model y = f(x)?

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
