Solve case 3.3 (I)(B) K = 4

Case 3.2 ())a) or Case 32 (ITb) 3.3 -Hypothesis Testing Question 2 (13 marks) () Each learner must solve one (1) of the following two (2) hypothesis testing cases listed below based on the Instructions given. For learners whose admission number ends with an odd number (1 3,5,7,9), solve case 3.3 (1)(8). For learners whose admission number ends with an even number (2,4.6,8,0), solve case 3.3 (1)(b). The sample size taken for each leamer is n=39-k, where k is your register number in your class register. For example, if your class register number Is 1, the sample size that you will select is n=39-1-38. Thus, you will select the first n=38 from the relevant sample data in Appendix | and perform the appropriate calculations. On the other hand, if your class register number is no. the sample size that you will select is n=39-10=29. Thus, you will Assignment Guide / BMS004/ Page _ select the first n-29 from the relevant sample data in Appendix t and perform the appropriate calculations. A company had been using a new Customer Relationship Management (CRM) system for the past 1 year to keep track of customers details and buying preferences to conduct customer analytics and targeted sales campaigns. The sales manager claimed that the average sales of lis customers had increased by more than $1.000 using the new system, To determine if the claim is true, the increase in sales of a random sample of customers was tracked and shown in a table in Appendix 1. Determine if the claim by the sales manager is true with a hypothesis test at 1 5 % level of significance (b) A supply chain company is evaluating if its warehouse management system (WMS) needs to be enhanced. Management has determined that if the average order fulfillment lime exceeds 130 minutes. its warehouse management system needs an enhancement To measure the average order fulfilment time, a study was commissioned. The data collected from a random sample of orders is shown in a table in Appendix 1. Determine if the warehouse management system (WMS) needs to be enhanced with a hypothesis test at 1% significance level.Observation P/E ratio of companies Customer satisfaction score (points) Increase in sales ($) Order fulfilment time (minutes) 11.2 74 1977 198 13.8 69 1072 230 13.9 74 574 164 16.7 79 782 273 15.9 60 1430 184 13.5 71 1669 206 12.9 69 1538 233 12.3 59 1674 188 14.9 60 720 260 10 15 72 992 333 11 16.7 70 1055 210 12 15 66 923 345 13 13.4 65 994 300 14 12.2 55 1955 120 15 15.1 62 1415 166 16 10.4 62 1113 141 17 12.5 55 684 151 18 18.9 80 1237 166 19 11.8 76 638 199
