Question#1 In a business study involving 100 firms, the number of employees per firm was recorded for each firm. What is the variable of interest in this study and how many observations are in the data set? By choosing a recent article related to a large US company, discuss the employment trends in that company. Is the company increasing employment or not as a result of the current economic conditions? Calculate the standard deviation for the data set provided in the 1st question. Describe the formula used and interpret the data. 2(b) Which of the following variables are qualitative variables? a) The color of IPhones sold by Apple b) The length of time required to solve a statistical problem c) The rating to a customer service call in a random survey is: poor, good or excellent. 1a. The following data has been recorded on the number of employees for 6 small firms: 12, 23, 23, 27, 34, 44. Calculate the mean, mode and range of the data. Provide the names of 1-2 leading statisticians that are related to the concepts described in this module. Are the names you found the same as other student’s picks? 1b. Provide a reason why the mean, mode, or range matters in real world application. The probability that a machine does not produce a defective object during a particular shift is 0.85. What is the complement of the event that a machine does not produce a defective item during that particular shift and what is the probability of that complementary event? 2a. Suppose to throw a dice, then calculate the probability that the number 5 appears on the face of the dice. Who was one of the first statisticians in the history that used these experiments to develop other mathematical concepts? Compare your answers with other student’s answers. 2b. Provide a real world example of when probability is necessary to use. Define and discuss the Socratic Method of inquiry and explain how Plato and Aristotle built on this model to form their own theories. define the concept of logical inquiry. How does this form of thought differ from the Socratic Method? Discuss generally what characteristics distinguish the Medieval era philosophers and their theories—were there common themes among them? What distinguishes this era from the Ancient schools of thought?

Question 1
In a business study involving 100 firms, the number of employees per firm was recorded for each firm. What is the variable of interest in this study and how many observations are in the data set? By choosing a recent article related to a large US company, discuss the employment trends in that company. Is the company increasing employment or not as a result of the current economic conditions?Calculate the standard deviation for the data set provided in the 1st question. Describe the formula used and interpret the data.
Given that the number of firms are 100 all of which have employees, these are key variables. In such a data set, the variables of interest will be the firms and the number of the employees that each of the firm have on their payroll. While most of the other companies are trying to cut back on employment, Apple Inc. is constantly increasing their employment rates. This has been the general trend since 2005 to this day.
14 + 17+ 21+ 32+ 34+ 46+ 60+ 72+ 80+ 92+110/11= 52.5
Mean is 52.5
(14-52.5)2+ (17-52.5) 2+(21-52.5) 2+(32-52.5) 2+(34-52.5) 2+(46-52.5) 2(60-52.5) 2+(72-52.5) 2+(80-52.5) 2+(92-52.5) 2+(110-52.5) 2 =10598.75
10598.75/10=1059.875
SD =32.5
The data sets are first added up and divided by their total number to give the mean. After which, the difference of the various sets from the mean is squared and the divided by the total number of sets minus one. This gives the standard deviation from the mean.
Question 2b
Which of the following variables are qualitative variables?
a) The color of IPhones sold by Apple
b) The length of time required to solve a statistical problem
c) The rating to a customer service call in a random survey is: poor, good or excellent
From the list of the variables, the rating to a customer service call in a random survey is the qualitative variable.
