You don't need to answer the first question 2, just refer to it when applying it to the SPSS question

2. Twenty users were asked to add a contact to a customer relationship management software (CRIvI) application. Eleven users completed the task on the existing version and nine different users comp1|ted the same task on the new enhanced version. The sample means are 3'? and 28 seconds, respectively. The sample standard deviations are 22.4 and 9.4 seconds, respectively. Is there enough evidence to conclude a difference in the average time for adding a contact between the two versions? Use the rejection point method. Use a = 0.05. 2. Consider Question 2. The study was conducted again, and the following are the data. w 18 12 44 35 35 21 78 9 38 2 18 10 16 5 22 38 40 30 77 ll 20 12 30 27 42 44 A. Using SPSS, compute the 95% condence interval. B. Use SPSS to test if there enough evidence to conclude a difference in the average time for adding a contact between the two versions? Use a = 0.05
