Scenаriо 2: A reseаrcher suspects thаt there is a direct relatiоnship between hand-eye cоordination and academic success in mathematics. A sample of n = 16 students who have demonstrated high performance on a 2nd grade mathematics achievement test is selected. These students are given a standardized hand-eye coordination task where the average score from this age group is μ = 55. Using α = .05, the researcher wants to know whether these students have hand-eye coordination scores that are significantly different from the general population. Type of t-test: H0: H1: Degrees of freedom (df):
