BCO127 APPLIED MANAGEMENT STATISTICS Final Task brief & rubrics Task Students are required to answer all the questions and develop an individual report addressing the specific tasks set out in the guideline below. Task briefing: The grades and the hours of study/week for the students attending a course of Statistics are the following: Student # Name 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 Anna Robert Catherina Daniel Emily Fred George Henry Ines Johanna Sara Paul Rose Maria Roger Peter Eve Tony Alexandra Albert Gender (0:male; 1:female) 1 0 1 0 1 0 0 0 1 1 1 0 1 1 0 0 1 0 1 0 Hours of study/ week 10 7 12 6 7 5 6 8 10 10 12 9 8 13 7 5 9 8 7 9 1) Do you think that boys and girls study the same time and get the same results? (25 points) Elaborate your answer using a Test of Significance: a. What do you think is the most appropriate Hypothesis Test? b. What is the Null Hypothesis? And Alternative Hypothesis? c. Calculate the P-values. What will be your decision? Grade 85 82 91 80 79 76 75 82 88 86 93 86 81 90 84 77 84 80 78 82 2) Use the list of random digits and choose a Simple Random Sample (SRS) of six. Start at the beginning of this list and attach labels to the names. What is the sample do you obtain? (15 points) Using this sample, do you conclude the same than in question 1) ? Justify your answer. (10 points) 3) Assuming the variable Grade is following a Normal Distribution, with the sample in 2) estimate the population mean with a Confidence interval of 80%, 95% and 99.9%. (20 points). 4) Determine the relationship between the hours of study and the grade. (30 points) a. Plotting a scatter diagram of the data, what does this suggest? b. Calculate the linear regression equation that best fits the data and explain the independent and dependent variables. c. Calculate the correlation coefficient and what does it mean. d. Estimate the grade if the time of study is 4.5 hours/week. Formalities: • • • • • • Word document. Wordcount: 1000-1500 words. Cover, Table of Contents, References and Appendix are excluded of the total wordcount. Font: Arial 12,5 pts. Text alignment: Justified.

Weight: This task is a 40% of total grade for this subject. It assesses the following learning outcomes. On successful completion of this course, students will be able to: 1. Design and explain statistical models, perform analysis and solve real-world problems. 2. Understand concepts, formulas, and techniques of statistics through applied examples. 3. Understand statistical language and develop statistical thinking. 4. Interpret results of statistical analysis. Rubrics.
