Program Plan Intro

Program plan:

1.inputStream variables used tostream file data.

2.while() loop is used to count total number and total leading number.

Program description:

The main purpose of the program is to test Benford’s Law. Read all the number from file then present the output of the percentage of the leading digits from the total numbers.

Generating statistics from a set of data is a task that computers love. In this assignment, you will be implementing a grade processing system that will generate the mean and standard deviation for a set of final exam grades. We will assume that final grades are stored in a list, where each entry in the list is a string with the following format: "studentNum-finalGrade%" The string represents the final exam mark (finalGrade) that the student (studentNum) achieved. For example, the cell below contains a list of final exam marks from two students. Student 1007089 achieved a mark of 91%, and student 1009989 achieved a mark of 77.5%. grades = ['1007089-91%','1009989-77.5%' ] We want to calculate the mean final exam mark from a list of grades. If we assume that we have N grades, the mean x can be calculated from the following formula: N-1 1 (1) i=0 The variable x; represents each grade in our list at index i. We assume that we start counting at 0. We also want to be able to calculate the…
Use python machine learning. A group of data scientists want to analyze some data. They already cleaned up the data, with the result being a Dataframe called X_train. The Dataframe X_train has 1058 rows and 13 columns. It has the below columns (picture attached on how it looks like): 'LotFrontage','LotArea','BsmtFinSF1', 'BsmtFinSF2', 'BsmtUnfSF','TotalBsmtSF','1stFlrSF', '2ndFlrSF', 'LowQualFinSF', 'GrLivArea','TotRmsAbvGrd','GarageArea','OpenPorchSF'   Answer the following questions: 1. Transform X_train using PCA. Assign the output to a variable X_train_pca. 2. What is wrong with above approach? Scale the data, then repeat the above.
A large company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9% their gross sales for that week. For example, a salesperson who sells $5,000 worth of merchandise in a week receives $200 plus 9% of $5,000, or a total of $650. You’ve been supplied with a list of the items sold by each salesperson. The values of these items are shown in the table below. Develop a Java application that inputs one salesperson's items sold for last week and calculates and displays that salesperson's earnings. There is no limit to the number of items that can be sold. Item Value 239.99 2 129.75 3 99.95 4 350.89 Objectives This assignment was designed to reinforce programming concepts from Chapter 4. In this assignment you will practice: • Using if-else statements Sample Runs Run: Run: Enter number sold of product #1: 20 Enter number sold of product #2: 30 Enter number sold of product #3: 0 Enter number sold of product #4: 45 Earnings this week: $2403.41 Enter number…
