Chapter 77.17Each year,Forbesmagazine publishes a list ofthe world’s richest people. In 2009, the six richestpeople, their citizenship, and their wealth (to thenearest billion dollars) are as shown in the followingtable. Consider these six people a population ofinterest:NameCitizenshipWealth ($ billion)William gates III (G)United States40Warren Buffett (B)United States38Carlos Slim Helu (H)Mexico35Lawrence Ellison (E)United States23Ingvar Kamprad (K)Sweden22Karl Albrecht (A)Germany22

a. Calculate the mean wealth, μ, of the six people.b. For sample size 2, construct a table similar toTable 7.2 on page 299 (height of players).c. Draw a dotplot for the sampling distribution ofthe sample mean for sample size 2.d. For a random sample size 2, what is the chancethat the sample mean will equal the

here is the problem I got when I coding,

it shows:

Exception in thread “main” java.util.InputMismatchException

at java.util.Scanner.throwFor(Unknown Source)

at java.util.Scanner.next(Unknown Source)

at java.util.Scanner.nextFloat(Unknown Source)

at FinalTemp.main(FinalTemp.java:17)

need help on this question above and some ideas of how to fulfilled the requirements below

######## The Requirements #####################

a) Read integer Fahrenheit temperatures from the user. You need to check whether the input is the correct one or not. If the user enters the incorrect number, ask it again.

b)

• The program should ask the user to continue or not. If the user wants to do the conversion again, use repetitive statements such as DO WHILE, FOR, or IF THEN ELSE to do the conversion again.
• Add comments to explain the functions of the program.
• Code the following display at the end of your program:

##################### Original Code Below ##########################

import java.util.Scanner;

public class FinalTemp{

  public static void main(String[] args) {

  String keyboard = “”;

  float f;

  double c;

  Scanner input = new Scanner(System.in);

  while (!keyboard.equals(“stop”)) {

  System.out.println(“”);

  System.out.println(“to quit, enter ‘stop’.”);

  System.out.print(“Enter the temperature in Fahrenheit: “);

  f=input.nextFloat();

  c=(f-32)*5.0/9.0;

  System.out.printf(“%.0f fahrenheit is %.2f celsius”, f, c);

  System.out.println(“”);

  }

  System.out.println(“”);

  System.out.println(“HELLO INSTRUCTOR Lee, THIS IS THE INF231 FINAL ASSIGNMENT FOR: Liwei Loh”);

  }
