A psychologist would like to determine whether people tend to select more positive traits to describe their close friend than a stranger. To test this, the psychologist chose two groups of individuals as participants. One group described their close friends while the other group described a stranger. The psychologist recorded the number of positive traits selected from a list of 100. Reported Sleep (hrs.) is given the attached file (question3_dataset.xls). Note that this file generates random numbers every time it is opened. Once you open the file, copy and paste the data you will work on below so that you have a copy of it. You can use "Paste Special" option in excel or Google sheets and choose "Values" if you want to save the data and comeback to it. If you are not familiar with this paste option, see instructions here. a) Copy and paste the data below b) What is the appropriate test to test the hypothesis? c) Compute the appropriate test. Report whether you retain or reject the null hypothesis and state your conclusion in terms of the verbal hypothesis.
