[Steps Shown] A sample of difference scores from a repeated-measures experiment has a mean of M D = 5 with a variance of s 2 = 64. If n = 4, is this sufficient

Question: A sample of difference scores from a repeated-measures experiment has a mean of M D = 5 with a variance of s 2 = 64.

  1. If n = 4, is this sufficient to reject the null hypothesis using a two-tailed test with α = .05?
  2. Would reject H 0 if n = 16? Again, assume a two-tailed test with α = .05.
  3. Explain how the size of the sample influences the likelihood of finding a significant mean difference.
