An engineer randomly inspected 140 rural bridges in a state and found that 50 had serious problems. What is a 95% confidence interval for the proportion of bridges in the state with serious problems? (Show work)

This program (in python) will display a set of authors and the number of novels written by each author in both a table and a histogram. You will ask the user for all of the information. Using what you learned about incremental development, use the following approach to create your program:

1. Prompt the user for the information about the table. First, ask for the title of this data set by prompting the user for a title for data. Output the title.
   
   Ex:

Enter a title for the data:
Number of Novels Authored
You entered: Number of Novels Authored

2. The table will have two columns; one for the authors and one for the number of novels. Prompt the user for the headers of two columns of the table. Output the column headers.
   
   Ex:

Enter the column 1 header:
Author name
You entered: Author name

Enter the column 2 header:
Number of novels
You entered: Number of novels

3. Prompt the user for data points. Data points must be in this format: string, int, representing the author and the number of novels written by the author. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in a list of strings. Store the integer components of the data points in a list of integers.
   
   Ex:

Enter a data point (-1 to stop input):
Jane Austen, 6
Author: Jane Austen
Number of Novel(s): 6

4. Perform error checking for the data point entries as follows:

• If entry has no comma and is not -1
• Output: Error: No comma in string.

If the error occurs, output the appropriate error message and prompt again for a valid data point. You can assume that if a comma is present, then the data point is entered correctly.
Ex:

Enter a data point (-1 to stop input):
Ernest Hemingway 9
Error: No comma in string.

Enter a data point (-1 to stop input):
Ernest Hemingway, 9
Author: Ernest Hemingway
Number of Novel(s): 9

5. Output the information in a formatted table. The title is right justified with a minimum field width value of 33. Column 1 has a minimum field width value of 20. Column 2 has a minimum field width value of 23.
   
   Ex:

        Number of Novels Authored
Author name         |       Number of novels
--------------------------------------------
Jane Austen         |                      6
Charles Dickens     |                     20
Ernest Hemingway    |                      9
Jack Kerouac        |                     22

Mark Twain          |                     11
Agatha Christie     |                     73
Ian Flemming        |                     14
J.K. Rowling        |                     14
Stephen King        |                     54
Oscar Wilde         |                      1

6. Output the information as a formatted histogram. Each name is right justified with a minimum field width value of 20.
   
   Ex:

         Jane Austen ******
     Charles Dickens ********************
    Ernest Hemingway *********
        Jack Kerouac **********************
 F. Scott Fitzgerald ********
        Mary Shelley *******
