PLEASE INCLUDE STEP-BY-STEP SOLUTION AND THE STATCRUNCH FILE/OUTPUT THANK YOU!

A polling company wants to test the time (in minutes) required to run two different versions of a new survey questionnaire to prepare costing options for its client. They select a random sample of 9 respondents and administer version A to them. A week later, they recontact the same respondents and administer them version B. The results (in minutes) to complete the two versions of the questionnaire for each respondent is presented in the Assign2Data.xlsx file.

Assign2Data:

Respondent	Version A	Version B	Vers.A-Vers. B
1	25	18	7
2	29	21	8
3	32	23	9
4	26	20	6
5	21	20	1
6	41	25	16
7	25	17	8
8	25	16	9
9	27	21	6

(a) Which approach is more appropriate to analyse these data - a paired data approach or two independent samples approach? Explain.

(b) Explain whether a parametric or nonparametric test is more appropriate to test if Version A takes longer time to administer than Version B (mean or median?).
