According to an article by George Will (San Jose Mercury News, Feb. 28, 2002), the average U.S. consumption per person per year of French Fries is 28 pounds. Suppose that you believe that the average in Santa Clara County is not 28 pounds. You randomly survey 50 people in this county. The sample average is 24 pounds with a sample standard deviation of 10 pounds. Conduct an appropriate hypothesis test.

1. This test is:

A. two-tailed

B. no-tailed

C. right-tailed

D. left-tailed

2. The p-value for this test is:

A. 0.0068

B. 0.0034

C. 0.0047

D. 0.0136

3. At the 5% level, the correct conclusion is:

A. The average consumption in Santa Clara County is not 28 pounds.

B. The average consumption in Santa Clara County is less than 28 pounds.

C. The average consumption in Santa Clara County is less than 24 pounds

D.  The average consumption in Santa Clara County is 24 pounds

Write a function that plots the following trajectory equations using python turtle graphics.

x = v*sin(A)*t

y = v*cos(A)*t -.5*(9.8)*t**2

Loop through t starting at 0 and increment by .1 until y<=0. (hint, while loop) Experiment with values of velocity V (1 to 20) and angle A (0 to 90) that gives you a good plot that does not go off the screen. Position the start of the plot at the left bottom of the screen

Write a 4-6 sentence summary explaining how you can use STL templates to create real world applications. In your summary, provide an example of a software project that you can create using STL templates and provide a brief explanation of the STL templates you will use to create this project.

After that you will implement the software project you described . Your application must be a unique project and must incorporate the use of an STL container and/or iterator and at least 7 STL algorithms with an option to exit. Your application must contain at least 8 menu options. You will decide how to implement these menu selections.

Her is the sample code how this project suppose to be.

A local library requested a program to help them organize their book collection. Their collection consists of 3500 books. They would like to be able to display all books by the author, so users could find specific book easier.

For this project, a menu-driven console was created to read data from a text file, and store the data in the vector container.

Each field in the text file was stored in a separate line. Starting the application triggered the creation of a vector and structs, where each struct will contain one book. Furthermore, the structs will contained the following information: author, title, publisher, description, ISBN, and year published fields which are pushed at the back of the vector.

When started, the application presents a welcome message with the current date, and a menu with the following menu items:

• Add new book: program adds the book to the vector and to the text file

• Remove book: program removes the book from the vector and from the text file

• Remove All: program deletes vector

• Search by author: Program prompts the user for the author’s name, search a vector for an author, and if found, the author’s name with the book title will be displayed to the user

• Search by ISBN Program prompts user for the ISBN number, searches a vector for given ISBN, and if found, the author’s name with the book title and ISBN number will be displayed to the user

• Sample code

  #include <iostream>
  #include <fstream>
  #include <string>
  #include <vector>
  

  using namespace std;
  

  struct book {
