23: The accountant of Manama Corporation has collected the following data on its copy machine costs for the last six months of the year. Month Number of copies Total copy cost July 3,500 $14,000 August 3,200 13,500 September 4,100 16,000 October 5,100 18,000 November 5,600 18,500 December 4,800 17,500 Requirements : 1- Use the regression analysis method to: a- Estimate the cost function (Y= F+vX). b- What percentage of the copy cost depends on number of copies? What portion of the fluctuation is not explained by that cost driver? You need to perform this using Excel. Submit the excel sheet along with your paper. 2- Using the high-low method, calculate the total fixed factory overhead cost and the variable factory overhead cost per direct labour hour and Prepare the cost function. 3. What would the total factory copy cost be at a level of 4,600 copies using each method above? 4. Which prediction method is the best method? Why?
Compound Probability
Compound probability can be defined as the probability of the two events which are independent. It can be defined as the multiplication of the probability of two events that are not dependent.
Tree diagram
Probability theory is a branch of mathematics that deals with the subject of probability. Although there are many different concepts of probability, probability theory expresses the definition mathematically through a series of axioms. Usually, these axioms express probability in terms of a probability space, which assigns a measure with values ranging from 0 to 1 to a set of outcomes known as the sample space. An event is a subset of these outcomes that is described.
Conditional Probability
By definition, the term probability is expressed as a part of mathematics where the chance of an event that may either occur or not is evaluated and expressed in numerical terms. The range of the value within which probability can be expressed is between 0 and 1. The higher the chance of an event occurring, the closer is its value to be 1. If the probability of an event is 1, it means that the event will happen under all considered circumstances. Similarly, if the probability is exactly 0, then no matter the situation, the event will never occur.
