Create a "Date" class that contains:

three private data members:
month
day
year
(I leave it to you to decide the type)
"setters" and "getters" for each of the data (6 functions in total)
One advantage of a "setter" is that it can provide error checking. Add assert statements to the setter to enforce reasonable conditions. For example, day might be restricted to between 1 and 31 inclusive.
one default constructor (no arguments)
one constructor with three arguments: month, day, and year
Add assert statements to enforce reasonable conditions.
a printDate function. This function will have no arguments and return void
a sameMonth function. This function will have one Date argument and a boolean return type
In main (in the following order):

instantiate one date object (date1) using the default constructor
use the getters to display the month, day, and year of date1 (should print the default values)
read keyboard input from the user for a month, day and year
use the setters to set the values of date1 to the values that came from the user
read keyboard input from the user for a second date
use the constructor with three arguments to instantiate date2 to the second date input from the user
print both objects using printDate
print a message to say if the two months are the same (testing the sameMonth function)
Your code should be in three files:

Date.h
contains the class definition
Date.cpp
includes "Date.h"
contains the functions for the class
main.cpp
includes "Date.h"
tests the class
Sample Output (Two Runs)

Getting in to a prestigious law school can have lasting effect’s on lawyer’s careers, thus the admission process is important. One measure that admissions officers look at is prospective law student’s LSAT scores. Because of that, companies that specialize in preparing students for the LSAT have sprouted up. Altair Test Preparation, in an effort to differentiate themselves from the rest and to assure their clients that they are being provided with what really is having an effect, have decided to conduct some research to identify what has the greatest impact on student’s LSAT scores. All companies advertise that the number of hours they give them study sessions is what makes a difference. Based on the results, Altair will either recommend the hours needed to obtain a “good” score vs an “excellent” score. (Good is 155, excellent is 169), or will decide to investigate other learning interventions, and academic counseling which might have a greater impact.

Altair collected a sample of 50 students, who in the previous year, were their clients and subsequently took the LSAT. The looked at the relationship between the number of hours they used the service, and their LSAT score. You, as the statistician, will run the analysis and make your recommendations to Altair Test Preparation.

Your report should have the following qualities:

  • What LSAT score would you predict for a student that used the service for 10 hours? What

    recommendation would you give the student concerning the number of hours they have used

    the service?

  • Your final conclusion should use both the 95% confidence and prediction intervals. Improper use

    of these and corresponding wrong/sloppy interpretations is highly penalized.

  • Use Data Analysis for Regression and the Regression Template provided on the course website

    for the intervals.
