Hi can somebody please assist me with the following questions based on the dataset that is attached. I have asked the question twice but both answers came back with the wrong numerical date being used. I only need assistance with question D,E and F.

This question is based on your work on MU123 up to and including Unit 4. An IT company develops software for the hospitality sector. It tests its code using an industry standard software package. Aiming to expand their business and be more competitive in the sector, the company has decided to pilot an inhouse software package to test its code. A company researcher wishes to compare the times taken for each package to complete tests. Both software packages were run on 20 occasions testing the same code. The researcher records the times taken on each occasion and these are shown in Table 1. Table 1 Comparison of detection times in minutes for the industry standard and inhouse software testing packages Test number Industry standard software package Inhouse software package 354 323 327 322 341 308 390 332 373 316 386 324 301 326 356 322 653 335 370 342 307 316 342 326 384 345 379 338 363 333 364 336 17 313 322 18 336 320 19 390 351 20 373 332 (a) (i) Which of the three types of investigation discussed on pages 177-9 of Unit 4 is this? Explain your answer briefly. [2] (ii) Are these primary or secondary data, from the researcher's point of view? Explain your answer briefly. [2] (b) Spend a few minutes scanning these datasets by eye. (i) List any three features you should be looking for when scanning datasets by eye. [3] (ii) Comment on whether or not you think there might be a problem with any of the most extreme values in each column. [3]
