Based upon the report from the Department of Game and Fish, a researcher wished to determine how much trout weigh in Trout Creek. A random sample of 5 trout where captured, weighed, tagged and released; the weights recorded in pounds were 2 lb, 4 lb, 6 lb, 7 lb, and 9 lb yielding the sample mean of 5.6 lbs and sample standard deviation of 2.7.
At the 10% level of significance, give the associated (positive)critical statistic accurate to two decimals.
