How did you get the variance for this problem ?
A medical researcher wants to test whether the mean cholesterol levels are the same for 3 treatment groups of subjects (with 18 total randomly selected subjects): those who take a new medication, those who follow a diet, and those who make no changes to medication or diet. They plan to use a 5% level of significance for their decision. Below is a partial Analysis of Variance table. Use it to answer the following questions deg of freedom Sum of Squares Mean Square F statistic Treatment Group 3.121 1.5607 Error 1.517 0.1011 Total 17 What are the degrees of freedom for the treatment groups? What are the degrees of freedom for the error? What is the F-statistic for this data (3 decimal places)
How many F ratios are figured in a two-way analysis of variance? 1 2 3 as many as there are cells in the design
We are interested in determining whether or not the variances of the sales at two music stores (A and B) are equal. A sample of 16 days of sales at store A has a sample variance of 20 while a sample of 26 days of sales from store B has a sample variance of 30. The test statistic is (A) 1.50 (B) 1.69 (C) 2.25 (D) 2.50
One-way or two-way refers to the number of independent variables (IV's) in your Analysis of Variance test. One-way has one independent variable (either discrete or continuous) and two-way has two independent variables (either discrete or continuous). For example, a one-way Analysis of Variance could have one IV (brand of cereal) and a two-way Analysis of Variance has two IV's (brand of cereal, calories). O True O False
What correctly represents the coefficient of determination in terms of the variance that is an output from the analysis of variance table?
What is the proportion of variance shared between the 2 variables? (How much of the variance in one variable can be predicted by the variance in the other variable?) Provided : mean 1 = 13.6 SD 1 = 2.26 Mean 2 = 102.7, SD= 11.36 Coefficient r = 0.47

If I roll two six-sided dice, what is the mean and variance of their difference? (note, the difference of 3 and 1 is 3 - 1 = 2, but the difference of 1 and 3 is 1-3 = -2) a) What is the mean?
