Question 253978
Given the following sample data of head injury to crash test dummies and a significance level of α = 0.05, test the claim 
that the four samples come from populations with the same mean (μ1 = μ2 = μ3 = μ4).

a. What is the sum of squares between groups?;;;;20912.3667 
b. What is the sum of squares within groups?;;;;;6970.7889 
c. What is the degrees of freedom between groups?;;;;;3 
d. What is the degrees of freedom within groups?;;;;;;16 
e. What is the F value?;;;;;;0.20546.. 
f. What is the F critical value?;;;;;? 
g. What is the p-value?0.8911.. 
h. Based on the p-value describe why you accept/reject the hypothesis.
Since the p-value is greater than alpha, do not reject Ho.
