Statistic Questions using PSPP

I will attach the whole assignment consists of total 3 questions. I have input the pre-task data required which is the data from 20 questionnaire into the PSPP. I will also attach the screenshot and the data itself for reference. Do take note the number of pages does not matter, this is a question and answer based type question. My deadline is tomorrow (26/9/2018) before 6pm (GMT+8). Would appreciate if anyone could help as due to time constraint im not able to do this assignment. Thank you!

The data file.sav seems to be unable to upload. Please let me know if I can send to you through other means. Thank you!
