A researcher conducts a repeated measures t-test with 10 subjects. If the estimated population variance of the difference scores is 20, what would the variance of the distribution of the means of difference scores be?

Forty-eight participants are divided into two different-sized groups and asked to play a game while very, very hungry. Given that their pooled variance estimate is 7.19, when conducting a t-test to compare the two groups scores, approximately what would the standard error of the distribution of sample mean differences be? cannot say based on the information given 0.15 0.77 0.39

A group of 36 Canadian ice-hockey fans watches one hockey game while imbibing Molson Canadian and eating ketchup chips and then a second game (with an one-week interval) while imbibing Labatt's Blue and eating Timbits (counterbalanced order). If the estimated variance of the population of difference scores is 18.11, approximately what is the standard error of the distribution of sample difference scores? 87 0.71 3.02 2.04

What is the variance of a random sample of size 5 that is taken with replacement from a population with mean = 15 and  variance = 10?

The mean of the distribution of sample means is equal to... the population mean the mean of the population times sigma the population variance the sample variance

Variance and Coefficient of Variation:Using the same data set: 5,8,12,14,18,20,22,255,8,12,14,18,20,22,25,Calculate the variance.Determine the coefficient of variation.
