Question

Please help me with all 4.

3. Below you are provided with the sum of squares, the variance, or the standard deviation for a sample, as well as the sample size. Given a value, provide values for the other measures. For example, if the standard deviation is provided, then you will have to work backwards” to calculate the variance, then the sum of squares. (2 pts total). A. SS = 2500 B. SS = S2 = S2 = S = S = 5 n = 26 n = 5 C. SS = D. SS = S2 = 100 s2 = S = S = .5 n = 51 n = 121

Answer 1

s^{​​​​​​2} = SS/(n-1)

A) s^{​​​​​​2} = 2500/25 = 100

s= √100 = 10

B) s^{​​​​​​2} =25

SS= 4 X 25 = 100

C) SS= 100/50 = 2

s= √100 = 10

D) s^{​​​​​​2} =0.25

SS= 0.25/120= 0.00208
