Many animals, including humans, tend to avoid direct eye contact and even patterns that look like eyes.
Question:
M = 37 minutes in the plain chamber with SS = 288 for a sample of n = 9 birds.
a. Is this sample sufficient to conclude that the eye-spots have a significant influence on the birds' behavior? Use a two-tailed test with a = .05.
b. Compute the estimated Cohen's d to measure the size of the treatment effect.
c. Construct the 95% confidence interval to estimate the mean amount of time spent on the plain side for the population of birds.
