Scenario 2: A researcher suspects that there is a direct relationship between hand-eye coordination 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):
