For a single sample t test, a sample of n=4 scores has SS=60. Which is the variance for this sample? s2=15s2=20s2=30s2=60 For a single sample t test, a sample of n=4 scores has a variance of s2=64. What is the estimated standard error for the sample mean? sM=4sM=1sM=16sM=2 A sample with a mean of M=40 and a variance of s2=12 has an estimated standard error of 2 points. How many scores are in the sample? n=10n=6n=3n=12 A researcher conducts a hypothesis test using a single sample of n=20 with M=34 and s2=36 from an unknown population. What is the df value for the t statistic? df=19df=21df=35df=12 One sample of n=8 scores has a variance of s2=6 and a second sample of n=8 scores has a variance of s2=10. If the pooled variance is computed for these two samples, then the value obtained for the variance will be closer to 10 than to 6 closer to 6 than to 10 exactly halfway between 6 and 10 This cannot be determined by the information provided.
