Calculating the degrees of freedom, the sample variance, and the estimated standard error for evaluations using the t statistic You are planning to evaluate the mean of a single continuous variable from a study with a sample of n = 45 using the t statistic. What are the degrees of freedom for the sample? O 46 O 45 O 43 O 44 With another study, where you also plan on evaluating a mean using the t statistic, you have a sample of n = 21 that has an SS of 500. What is the variance for the sample? O 250,000 O 5.00 O 22.36 O 25 For a sample of n = 25 that has a sample variance of 400, what is the estimated standard error for the sample? O 16 O 17 O 4.08 O 4
