Do an analysis of a real data set and also mention where did you find the data set. Please do analysis completely in R studio. A basic requirement for the data set is that it includes one response variable and at least two predictor variables.The main objectives of this question are• to identify a suitable data set,• to come up with meaningful research questions based on the data,• to experience some of the problems encountered when analyzing real data,Also mention:• Where I find the data set?• Why the problem is of interest?• Which method or model is appropriate to this problem?• How do I apply the method to analysis the data set?• What is my conclusion?

Question #1: What patterns do you notice in the time series plot of average annual airfare from 2004 to 2018? (a. horizontal pattern, b. clear upward trend, c. clear seasonal effects, d. clear downward trend) 2) Use a simple moving average with n = 3 (3 years) to calculate a forecast for the average airfare in 2019. Question #2: What is the 2019 forecast for average airfare using the simple moving average technique? (Round to two decimal places) 3) Based on the predicted values up to 2018, calculate accuracy measures (MAE, MSE, RMSE, and MAPE) for the simple moving average method. Question #3: What is the MAE for the simple moving average method?(Round to two decimal places) 4) Use a simple…
Consider a school system in which data is recorded about the movie industry. The data requirements are summarized as follows: Each subject is owned by a department and each department ismanaged by a teacher, called Head of Department (HOD). Eachdepartment has a name and a unique code number. Each subjecthas a name, unique number and credit value. All teachers have aunique ID. A HOD cannot manage more than one department at atime. Also, a HOD does not teach subjects. A subject cannot betaught by more than one teacher. Finally, the system needs toknow each student’s contact details, including, full name, studentID, address, age and gender, as well as date of enrolment in thesubject. Design an Entity-Relationship diagram for the movie database

Damon Davis was creating the Drano Plumbing Company's spreadsheet. He determined that the net income would be $50,000. When he tallied the columns on the Balance Sheet, the totals were as follows: debit, $400,000; and credit, $300,000. What was the most likely reason for this discrepancy? If this was not the case, how should he proceed to determine the source of the error?

decision_trees.ipynb [Part 2] 1. Pima Indian Diabetes Dataset The Pima Indians Diabetes Data Set was developed by the United States National Institute of Diabetes and Digestive and Kidney Diseases. Astonishingly, over 30% of Pima people develop diabetes. In contrast, the diabetes rate in the United States is 8.3% and in China it is 4.2%. Each instance in the dataset represents information about a Pima woman over the age of 21 and belonged to one of two classes: a person who developed diabetes within five years, or a person that did not. There are eight attributes in addition to the column representing whether or not they developed diabetes: The number of times the woman was pregnant Plasma glucose concentration a 2 hours in an oral glucose tolerance test Diastolic blood pressure (mm Hg) Triceps skin fold thickness (mm) 2-Hour serum insulin (mu U/ml) Body mass index (weight in kg/(height in m)^2) Diabetes pedigree function Age Whether they got diabetes or not (0 = no, 1 = yes) We…
