PROBLEM

A new software package is being developed and tested to help analysts reduce the time required to design, develop, and implement a new information system. To evaluate the benefits of the new software package, a random sample of 24 systems analysts is selected. Each analyst is given specifications for the new information system. Twelve analysts are instructed to produce the information system by using current technology. The other 12 analysts are trained in the use of the new software package to be used to produce the information system. The following data represent the completion times:

Current Technology New Software

300 274

280 220

344 308

385 336

372 198

360 300

288 315

321 258

376 318

290 310

301 332

283 263

Using a .025 level of significance, test whether the current technology took longer than the new software to complete the project. Show the following in your report:

1.Ho & Ha

2.p-value

3.Reject/don't reject Ho based on comparison of p-value to alpha.

4.Your conclusion, specific to the problem statement with respect to whether the new software should be replacing the current technology
