Hello again. I am learning this fascinating topic of Linear Regression. Here are some exercises and practice scenarios. 1) In this assignment’s segment, we will use the following regression equation  Y = a + bX +eWhere:Y is the value of the Dependent variable (Y), what is being predicted or explained a or Alpha, a constant; equals the value of […]

Today we have three different scenarios to test the random samples and probability distributions. A. Consider a population consisting of the following values, which represents the number of ice cream purchases during the academic year for each of the five housemates.8, 14, 16, 10, 11 a. Compute the mean of this population.b. Select a random […]

Unfortunately this week, I wasn’t able to complete my assignment. However, I have taken the time to study the class, and use some of the responses from the professor. Here is the questions and answers. First Question: The director of manufacturing at a cookies needs to determine whether a new machine is production a particular […]

Here are some exercises where I will be applying the Probability Theory. I will be evaluating the event A, event B and both events A. Based on Table 1 What is the probability of: B B1 A 10 20 A1 20 40 Table of events A1. Event A (Row values) A = 30/90 = 1/3 = […]

I have two data sets consisting of 7 observations each: Set#1: 10, 2, 3, 2, 4, 2, 5 Set#2: 20, 12, 13, 12, 14, 12, 15 For each, I will compute the Central Tendency and Variation. These measures are fundamental statistical concepts that I need to master on my journey to understand advanced analytics. A […]

Hello, today I have a simple example to show you how I have created a simple R function that will display the mean or average from a vector. I am creating a vector variable called ‘assignment2.’ Having variables assigned like this will make calculations easier.  assignment2<- c(6,18,14,22,27,17,22,20,22)   Now, I am ready to calculate the mean […]
