Question details

Group Statistics depression status of participants Mean Std. Deviation mean number of hours Depressed patient slept for 3 nights 8 6.9125 43895 Control 8 7.5500 52099 Group Statistics depression status of participants Std. Eror Mean mean number of hours Depressed patient slept for 3 nights 15519 Control .18420 Independent Samples Test Levenes Test for Equality of Variances t-test for Equality . Sig mean number of hours slept for 3 nights Equal variances assumec .008 .929 -2.647 Equal variances not assumed -2.647

2. Look at the Independent samples t-test table to get your t calculated, df, and significance. Read the line that says “equal variances assumed”. Remember that significance level will appear in the Sig (2-tailed) column. Any value that is smaller than .05 will be significant at the .05 level or higher. In a sentence describe the results and report them in APA style, including r2 and evaluation (you will need to calculate r2 by hand).

3. What type of error in hypothesis testing is possible given the above result? How likely is this error given r2?
