Program Plan: Include the required header files. Create class Date. The class definition will contain prototypes for member function Date like setDate. The private integer members month, day and year. A member function nextDay is included to increment the day by one. Program Description: /Program that tests function nextDay in a loop which prints the date during each iteration./ Date class declaration Here, the class is Date which declares the functions setDate()and nextDay().

Chapter 9, Problem 9.8E

Program Plan Intro

Program Plan:

Include the required header files.

Create class Date.

The class definition will contain prototypes for member function Date like setDate.

The private integer members month, day and year.

A member function nextDay is included to increment the day by one.

Program Description:

/Program that tests function nextDay in a loop which prints the date during each iteration./

Date class declaration

Here, the class is Date which declares the functions setDate()and nextDay().

Question 1 Generate a random sample of standard lognormal data (rlnorm()) for sample size n = 100. Construct histogram estimates of density for this sample using Sturges’ Rule, Scott’s Normal Reference Rule, and the FD Rule. Question 2 Construct a frequency polygon density estimate for the sample in Question 1, using bin width determined by Sturges’ Rule.
