In a one-sample t-test with sample size n = 8, observed statistic t = -1.14, and estimated standard error sM = 4.14, find the effect size in terms of proportion of variation explained. -0.275 0.140 0.157 0.126 Consider a population of N = 4 individuals, {23 24 25 26}. What is the expected value of the sample mean for a sample of n = 2 observations? (It isn't required, but if it helps, you may assume that sampling is done with replacement.) Cannot be determined Approximately but not exactly 24.5 Exactly 24.5 Approximately but not exactly 25.19
