A recent drug survey showed an increase in the use of drugs and alcohol among local...

A recent drug survey showed an increase in the use of drugs and alcohol among local high school seniors as compared to the national percent. Suppose that a survey of 100 local seniors and 100 national seniors is conducted to see if the proportion of drug and alcohol use is higher locally than nationally. Locally, 67 seniors reported using drugs or alcohol within the past month, while 63 national seniors reported using them. Conduct a hypothesis test at the 5% level.

NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)

  • Part (d)

    State the distribution to use for the test. (Round your answers to four decimal places.)

    P'localP'national

    ~
    ,
  • Part (e)

    What is the test statistic? (If using the z distribution round your answer to two decimal places, and if using the t distribution round your answer to three decimal places.)
    ---Select---tz =

  • Part (f)

    What is the p-value? (Round your answer to four decimal places.)


    Explain what the p-value means for this problem.
  • If H0is false, then there is a chance equal to the p-value that the proportion of students who use drugs and alcohol locally is at least 0.04 more than the proportion of students who use drugs and alcohol nationally.
  • If H0is true, then there is a chance equal to the p-value that the proportion of students who use drugs and alcohol locally is 0.04 less than the proportion of students who use drugs and alcohol nationally.    
  • If H0is true, then there is a chance equal to the p-value that the proportion of students who use drugs and alcohol locally is at least 0.04 more than the proportion of students who use drugs and alcohol nationally.
  • If H0is false, then there is a chance equal to the p-value that the proportion of students who use drugs and alcohol locally is 0.04 less than the proportion of students who use drugs and alcohol nationally.
  • Part (g)

    Sketch a picture of this situation. Label and scale the horizontal axis and shade the region(s) corresponding to the p-value.

  • Part (h)

    Indicate the correct decision ("reject" or "do not reject" the null hypothesis), the reason for it, and write an appropriate conclusion.(i) Alpha (Enter an exact number as an integer, fraction, or decimal.)
    α = .05

    (ii) Decision:

    reject the null hypothesis

  • do not reject the null hypothesis    


    (iii) Reason for decision:

    Since p-value > α, we do not reject the null hypothesis.

  • Since p-value > α, we reject the null hypothesis.   

  • Since p-value < α, we reject the null hypothesis.

  • Since p-value < α, we do not reject the null hypothesis.


    (iv) Conclusion:

    There is sufficient evidence to show that the proportion of local seniors using drugs and alcohol locally is higher than the proportion of seniors using drugs and alcohol nationally.

  • There is not sufficient evidence to show that the proportion of local seniors using drugs and alcohol locally is higher than the proportion of seniors using drugs and alcohol nationally.    

  • Part (i)

    Explain how you determined which distribution to use.

    The standard normal distribution will be used because the samples involve the difference in proportions.

  • The t-distribution will be used because the samples are independent and the population standard deviation is not known.

  •     The t-distribution will be used because the samples are dependent.

  • The standard normal distribution will be used because the samples are independent and the population standard deviation is known.

I have the function call showGroceries(list); I need to create a new prototype above int main that provides:

  • return type

  • function name

  • parameter(s) type(s)

Then copy-and-paste the prototype below int main. Give the parameter a name and then implement the function so that it takes the vector of strings and displays it so that a vector with the values:

{"milk", "bread", "corn"}

would display as:

Grocery list

1. milk

2. bread

3. corn

However, if there is nothing in the vector, instead it should display:

No need for groceries!

I have the following code

#include <iostream>
#include <vector>
using namespace std;

// function prototypes
char chooseMenu();
vector <string> addItem(vector <string>);


// main program
int main() {
vector <string> list;
char choice;
  
cout << "Welcome to Grocery List Manager\n";
cout << "===============================\n";
do{
choice = chooseMenu();
if( choice == 'a' || choice == 'A' ){
list = addItem(list);
}
}while( choice != 'q' && choice != 'Q' );
  
showGroceries(list);
  
return 0;
}

// function definitions

char chooseMenu()
{
char input;
// Menu input/output
cout << "Menu\n----\n";
cout << "(A)dd item\n";
cout << "(Q)uit\n";

cin >> input;
cin.ignore();
return input;
}

vector <string> addItem(vector <string>A)
{
string input;
// item input/output
cout << "Enter item:\n";
getline(cin,input);

A.push_back(input);
return A;
}

1)  Write a python program that opens a file, reads all of the lines into a list of strings, and closes the file. Use the Readlines() method. Test your programing using the names.txt file provided.
2) Convert the program into a function called loadFile, that receives the file name as a parameter and returns a list of strings.
3) Write a main routine that calls loadFIle three times to load the three data files given into three lists. Then choose a random element from the title list, two from the name list, and one from the descriptor list to generate a name. Print the name be in the form shown (you have to add the "the"):
title name name the descriptor
For example:
King Ludovicus Botolf the Bowman
Print the name to the screen.   
Submit your python file (.py) to Sakai

Part 2: Writing Files (Optional Extra Credit 20 pts)
Modify the program to generate 10 names and store them in a list.
Write a function, dumpFile that writes the list to a file called "CharacterNames.txt" There should be one Character Name on each line in the file.
Test the program to be sure it works

Im stumped at number 2

here is what i have for number 1

lines = f.readlines()
for line in range(len(lines)):
lines[line] = lines[line].rstrip()
