8. Based on the data used to produce figure 2, assume that researchers found the following of 95% confidence interval (CI) in the lower end and upper end for "sleep quality", "feeling following wakefulness" and "getting into sleep" domains of Leeds Sleep Evaluation Questionnaire (LSEQ). Leeds Sleep Evaluation Questionnaire domains 95% CI Sleep Quality (SQ) at Day 7 (Worse vs. Better) 0.65 to 82.58 Feeling following wakefulness (FFW) at Day 3 (Tired vs. Alert) 15 to 100 Getting into sleep (GTS) at Day 1 (More difficult vs. Easier) -10 to 70.24 Hint: higher score indicates better LSEQ domains. a. Based on these 95% CIs shown in the table above, which LSEQ domains are statistically significant? How did you know these were statistically significant? Do you reject or fail to reject null hypotheses? (2 points) b. How would you explain the significant findings to a lay person? (1 point)50 100 150 200 GTS Day 1 p=0.004 p=0.529 Day 2 p
