1. Suppose a random sample of 500 adults from Santa Clara County answered this question: “in general, do you believe in ghosts?” 225 responded that they believe in ghosts. Test whether it is plausible that, if you could ask all adults in the Santa Clara County this question, less than half would say they believe in ghosts. Use the significance level of 0.01 for this test. Do not forget to follow those five steps.

I need to be able to store 5000 names into an array. I currently have a code that generates one random name. I just need to generate an array of 5000 the same way.

#include <cstdlib>
#include <ctime>
#include <iostream>
#include <iomanip>

using namespace std;

string RandomFirstGen(int namelength);

int main(){

srand(time(NULL));
int namelength = rand()%(16-8+1)+8;
cout<<"name is: "<<RandomFirstGen(namelength)<<endl;

return 0;
}

string RandomFirstGen(int namelength){
for (int i=0; i<=5000 ; i++){
const int MAX = 26;
char alphabet[MAX] = {
'a', 'b', 'c', 'd', 'e', 'f', 'g',
'h', 'i', 'j', 'k', 'l', 'm', 'n',

string name = "";
for (int i = 0; i < namelength; i++)

The following is a chart of 25 baseball players' salaries and statistics from 2016.

In order to have correlation with 95% significance, what is the critical r-value that we would like to have?  

(Round to three decimal places for all answers on this assignment.)

RBI vs. Salary

Complete a correlation analysis, using RBI's as the x-value and salary as the y-value.

Correlation coefficient:

Regression Equation: y=y=    

Do you have significant correlation? Select an answer Yes No

HR vs. Salary

Complete a correlation analysis, using HR's as the x-value and salary as the y-value.

Correlation coefficient:

Regression Equation: y=y=       

Do you have significant correlation? Select an answer Yes No   

AVG vs. Salary

Complete a correlation analysis, using AVG as the x-value and salary as the y-value.

Correlation coefficient:   

Regression Equation: y=y=       

Do you have significant correlation? Select an answer Yes No

Prediction

Based on your analysis, if you had to predict a player's salary, which method would be the best? Select an answer Regression equation with RBI's Regression equation with HR's Regression equation with AVG The average of the 25 salaries

Using that method, predict the salary for Ryan Braun. His stats were:

RBI: 91

HR: 31

AVG: 0.305

Based on your analysis, his predicted salary would be: $ million  

His actual salary was $20.000 million.
