A craft store offers a knitting kit that purports to be so good at teaching you to knit that you will have completed your first sweater in only one day (we'll assume they mean 24 hours). In order to test the validity of this claim, they enlist the help of five willing volunteers. Each volunteer takes home a kit and records how long it takes them to complete the sweater. Their times are (in hours): 26, 38, 62, 22, 45. What should the store conclude about this knitting kit? Calculate t, d (effect size), and the 95% confidence interval. Use the .05 level.
