Task 3: Networking [15 marks] The retailer has seen a shift in the way in which consumers purchase items, such as computer, video conferencing and vlogging peripherals. Online retailing now accounts for over 80% of their sales and, to reflect this change, the retailer has decided to convert some of its retail space into warehouse space. This conversion project consists of 11 activities. For example, Activity E takes 4 weeks to complete and can only be started after Activity B has been completed. Information on the 11 activities is outlined on the precedence table (Table 3) below.

With reference to Table 3, construct a network diagram by going through the forward and backward passes. You may draw your network diagram in Excel or Word. The network diagram needs to be copied into your Word file. 2. Identify the critical path and duration of the project. 3. Comment on the distinction between critical and non-critical activities. Task 4: Probability [6 marks] In a recent survey, 60% of respondents were female and 20% of all female respondents were working part-time. In total, just 18% of respondents work part-time. Required for Task 4 (Comments for task 4 should not exceed 50 words in total.) 1. Construct a contingency table by using the information above. 2. With reference to the contingency table prepared under (1) above, what is the chance that a respondent chosen at random is male and works full-time? Use the correct notation and state the problem in full
