Question 4.16 LAB: Warm up: Drawing a right triangle I am unable to figure out this lab, please help. This program will output a right triangle based on user specified height triangle_height and symbol triangle_char. (1) The given program outputs a fixed-height triangle using a * character. Modify the given program to output a right triangle that instead uses the user-specified triangle_char character. (2) Modify the program to use a loop to output a right triangle of height triangle_height. The first line will have one user-specified character, such as % or *. Each subsequent line will have one additional user-specified character until the number in the triangle's base reaches triangle_height. Output a space after each user-specified character, including a line's last user-specified character.

MUST BE IN PYTHON As you are preparing for your final text game project submission, the use of dictionaries, decision branching, and loops will be an important part of your solution. This milestone will help guide you through the steps of moving from your pseudocode or flowchart to code within the PyCharm integrated development environment (IDE). You will be working with the same text-based game scenario from Projects One and Two. In this milestone, you will develop code for a simplified version of the sample dragon-themed game. The simplified version involves moving between a few rooms and being able to exit the game with an “exit” command. In the simplified version, there are no items, inventory, or villain. Developing this simplified version of the game supports an important programming strategy: working on code in small iterations at a time. Completing this milestone will give you a head start on your work to complete the game for Project Two. Prompt For this milestone, you will be submitting a working draft of the code for a simplified version of the text-based game that you are developing for Project Two. You will focus on displaying how a room dictionary works with the “move” commands. This will include the if, else, and elif statements that move the adventurer from one room to another. Before beginning this milestone, it is important to understand the required functionality for this simplified version of the game. The game should prompt the player to enter commands to either move between rooms or exit the game. Review the Milestone Simplified Dragon Text Game Video and the Milestone Simplified Text Game Flowchart to see an example of the simplified version of the game. A video transcript is available: Transcript for Milestone Simplified Dragon Text Game Video. IMPORTANT: The “Move Between Rooms” process in the Milestone Simplified Text Game Flowchart is intentionally vague. You designed a more detailed flowchart or pseudocode for this process as a part of your work on Project One. Think about how your design will fit into this larger flowchart. In PyCharm, create a new code file titled “ModuleSixMilestone.py.” At the top of the file, include a comment with your name. As you develop your code, you must use industry standard best practices, including in-line comments and appropriate naming conventions, to enhance the readability and maintainability of the code. Next, copy the following dictionary into your PY file. This dictionary links rooms to one another and will be used to store all possible moves per room, in order to properly validate player commands (input). This will allow the player to move only between rooms that are linked. Note: For this milestone, you are being given a dictionary and map for a simplified version of the dragon-themed game. Make sure to read the code carefully so that you understand how it works. In Project Two, you will create your own dictionary based on your designs. #A dictionary for the simplified dragon text game #The dictionary links a room to other rooms. rooms = { 'Great Hall': {'South': 'Bedroom'}, 'Bedroom': {'North': 'Great Hall', 'East': 'Cellar'}, 'Cellar': {'West': 'Bedroom'} } Next, you will develop code to meet the required functionality, by prompting the player to enter commands to move between the rooms or exit the game. To achieve this, you must develop the following: A gameplay loop that includes: Output that displays the room the player is currently in Decision branching that tells the game how to handle the different commands. The commands can be to either move between rooms (such as go North, South, East, or West) or exit. If the player enters a valid “move” command, the game should use the dictionary to move them into the new room. If the player enters “exit,” the game should set their room to a room called “exit.” If the player enters an invalid command, the game should output an error message to the player (input validation). A way to end the gameplay loop once the player is in the “exit” room TIP: Use the pseudocode or flowchart that you designed in Step #4 of Project One to help you develop your code. As you develop, you should debug your code to minimize errors and enhance functionality. After you have developed all of your code, be sure to run the code to test and make sure it is working correctly. What happens if the player enters a valid direction? Does the game move them to the correct room? What happens if the player enters an invalid direction? Does the game provide the correct output? Can the player exit the game? Guidelines for Submission Submit your “ModuleSixAssignment.py” file. Be sure to include your name in a comment at the top of the code file. #A dictionary for the simplified dragon text game #The dictionary links a room to other rooms. rooms = { Great Hall': {'South': 'Bedroom'), Bedroom': {'North': 'Great Hall', 'East': 'Cellar'}, 'Cellar': {'West': Bedroom} } Great Hall North South East Bedroom Cellar West

Biostatistics ESSAY A firm investigates the length of telephone conversations of their office staff. Ten consecutive conversations had lengths, in minutes: 10.7, 9.5, 11.1, 7.8, 11.9, 4.1, 10.0, 9.2, 6.5, 9.2. Derive a 95% confidence interval for the mean conversation length. Test whether the mean length of a conversation is eight minutes.(25 MARKS)

P3.5 The sales revenue, food cost of sales, and guests served for a small fast- food carryout division of a restaurant for the past six months are given below. Sales Month Cost of Revenue Guests Served Sales, Food 1 2. 4 $258,200 274,800 285,600 289,400 298,300 304,600 $ 96,200 104,300 110,500 113,100 118,900 123,700 10,200 10,400 10,300 10,100 10,400 10,500 6 For each of the six months calculate average check and average costs of sales food. Using these averages, calculate an index number. Set the in- dex for month 1 at 100 and complete index numbers for the remaining five months. With the index numbers identified, convert sales revenue and cost of sales food from historic to current dollars.

A cylindrical rock sample has a length of 6 cm, a diameter of 4 cm, and a dry weight of 166.4 g. When fully saturated with an oil of density 0.85 g/cm3, the weight of this sample is 176.9 g. Assuming constant temperature, find: i) The porosity of the sample ii) The pore compressibility of the sample, given that 0.2 cm of oil leaves the sample when a pressure of 3200 psig is applied on it iii) The amount of oil that can be extracted from the sample when a pressure of 2000 psig is applied on it
