1Using and Managing Data and InformationJuly cohort (2019 – 2020)BA3020QA – Assignment 3Task 1 (25 Marks)A supermarket manager wanted to investigate the profile of shoppers resistantto the use of self-checkout counters available at the store he manages and tofind out the reasons behind their resistance. He asks three of his staff toconduct a survey among customers using the store in Sheffield Hallam areaduring a quiet working day in October of 2019 as they exited the store.The short questionnaire used for the survey as well as the data collected canbe found on an Excel file named “SCC”. There are two worksheets, one forthe questionnaire used and the other worksheet for the raw data collectedfrom the customers. The data worksheet has 18 columns. Column A“Customer” is simply a column to identify the customer surveyed – Customer1, Customer 2 etc… Each of the other 17 columns refer to a question –Column B refers to the gender question, Column C refers to the age questionetc…The manager has employed you as data analyst to conduct this investigation.Your analysis should use the statistical facilities on Excel as required below.Required:1. Label the codes for the categories of the following variables:• Gender• Age• Education• Are you a regular user of self-checkoutNote to students:There are FIVE tasks and you are expected to complete all of them.You are required to transfer the work of all tasks on to a single wordprocessed MS Word file and upload it on Turnitin, which is thesubmission of this assignment. The deadline for this assignment is(Monday 19th April 2021 before 3pm).22. Produce frequency and percentage frequency tables for each of the followingvariables:• Gender• Education• Age• SCC user• Spending (£) For this last quantitative variable, the categories should be asfollows: 140 3. Draw the graphical representation for each of the following variables:• Education (Pie chart)• Age (Bar chart)• Spending (Histogram) using the following categories: 140 • Spending (Box and whisker) graph4. Consider now the variable “Spending (£)”.• Calculate the minimum, maximum, median, quartiles and the mean averagestatistics.Note:The tasks and all their requirements should be clearly separated (preferablyeach task starts on a separate page). All variables should be clearly namedand their correct categories clearly labelled. Graphs should be appropriateand correctly labelled and each of them on the same page. Any calculationsshould be clearly presented and explained.3Task 2 (20 Marks)A plumber has decided to use the techniques of project management in orderto plan a job. He knew all the different activities of the job, their precedenceand their average durations. They are shown on the table below. ActivityDuration(days)PrecedingactivitiesA3NoneB4NoneC4AD7AE2B and C Required:1. Draw a network diagram representing the sequence of activities and thedependence between them.2. Determine how long it will take to complete the job by conducting theforward pass3. By conducting the backward pass, identify the critical path and the noncritical path(s).Note:The work for this task should be produced using Word drawing facilities. Theforward and backward passes should be clearly shown on the diagram. Thecalculations should be shown next to the network diagram.4Task 3 (25 Marks)The quarterly sales figures for the number of shoes (pairs) sold at a shoe shopis shown on the table below. YearQuarterSales20171239223531914213201812452237319542182019125022413199421920201156214931054125 Required:1. Draw a line graph to represent the sales figures.2. Calculate the moving averages.3. Calculate the centre moving averages4. Present the original sales data and the trend of sales figures on the same linegraph.5Task 4 (15 Marks)The following information relates to the probability of two differentmanagers selecting a salesperson for a job:Probability of Manager Sam choosing a Salesperson is 0.5Probability of Manager Alex choosing a Salesperson is 0.3Over the last 10 working days, Manager Sam has worked for 6 days andManager Alex worked 4 days. Only one manager works in a day.Required:Build a Tree diagram to show the probabilities of a Salesperson beingselected.Show the different branches of the Tree diagram with all the calculations.Include in the Tree diagram the overall probabilities.6Task 5 (15 Marks)A small cheese maker specialises in two types of cheese – Brie and Goudathat he makes and sells in packets of 400 grams. The cheese maker hasestimated that each packet of Brie uses 1.8 litres of special milk and 100grams of special salt. For the Gouda cheese packet, the amounts of specialmilk and salt needed are 1.2 litre and 150 grams respectively. The cheesemaker has a limited supply of special milk and salt and a maximum of only120 litres of milk and 12000 grams of salt is made available each week. Onceproduced and sold, the Brie packet returns a £5 profit and £4 profit for theGouda cheese.Required:1. Enter the information on the table below into an Excel file. You should alsoinsert an appropriate formula for “Total profit” and quantity “Used” for eachof the “milk” and “salt” resource in the cells as indicated below.
