Pertaining to Question one, I am unable to solve the program.I have attached the assignment questions into the file section.Please take note of the following typo errors in the questionaire:1. The late penalty stated in Table 1 should be 20%.2. Remove the duplicate methods in the Truck and Car Class UML diagram in Figure 1.3. Page 5, (b) second bullet, remove the following: " (by default, set number of child seats to 0 for car and set the driver to false for truck when the object is created). "Please help me! I will need to submit the documents before Monday.

CONFIDENCE INTERVALSOne of the most popular ways to estimate an unknown parameter is the confidence interval. Instead of just using a point estimate, it gives an interval estimate. This gives more information about the unknown parameter. In this assignment, we will examine confidence interval. Download the dataset JNJ.csv from the course ,datawebsite.Using R, compute the sample mean of closing price of Johnson and Johnson's (JNJ) daily stock prices.Using R, compute the standard deviation. Also, compute the 90%, 95%, and 99% confidence intervals for the true mean closing JNJ stock price. Based on 3, discuss the pattern you see from these three confidence intervals and explain why such a pattern exists.What is the advantage(s) and disadvantage(s) of increasing the confidence levels? Explain.Interpret the confidence intervals you've calculated from part 3.Using a Word document, show the relevant calculations as well as the answers/solution. Copy the screenshots of the R output and paste them into the Word document. Your screenshot must include the current date using the function Sys.Date(

Assignment: Lab Exercise 6Python: Math CalculatorPython AssignmentThe objectives of this lab assignment are as follows:Declare variablesUse commentsUse arithmetic operatorsReceive input from the userOutput data to the consoleApply conditional logicConvert string value to floatSkills RequiredTo properly complete this assignment, you will need to apply the following skills:Read string input from the console and convert input to required numeric data-typesUnderstand the if / elif / else constructOutput information back to the userAssignment User StoryAs a user I want an application that will allow a user to calculate either the sum of two numbers (add), the difference between two numbers (subtract), the product of two numbers (multiply), or the quotient of two numbers (division).Assignment RequirementsIn this application you will prompt the user for one of four math calculations to perform: add, subtract, multiple, divide. Next, you will prompt the user for two numbers with which to operate. You will then perform the appropriate calculation deriving a resulting number. Finally, you will print the calculation performed with the result.This assignment combines operations of prompting and receiving input from the user with conditional logic to perform a specific function based on those inputs. Finally, this assignment outputs information back to the user.Important: you must realize that all input received from the user is assigned the data-type of string. Therefore, you must convert the numeric values received from the user to float data-types.When complete, your output should be as pictured below:Example of Add operation:Example of Divide operation:Example of Invalid option entry:Technical/Grading RequirementsYou must ensure that the application you submit meets all the technical/grading requirements. Your grade will be based on how well your application follows these requirements:The name of your application will be Calculator.pyYou must have a set of comments at the top of the program that identifies the programmer, date, and name of the program file. Furthermore, you must provide a description of what this program is and what it does. Each of these comments must be on individual lines.You must receive the option the user wishes to perform into a variable. You will then prompt the user for two numbers on which the specified operation will performed.If the user enters any option other than what is expected for add, subtract, multiply, or divide they will be notified that they have entered an invalid option.Your output must include the calculation plus the result.
