For the variance of a sample mean RV, taken from an infinite population whose mean is 10 and standard deviation is 2, to be equal to 1, the sample size should be Select one: 16 10 32 None 4

In order to use the defining formula for variance, we must calculate  (x − x)2  for each data value in the data set  14, 18, 22, 26, 33.  Use the values in the data set and the mean  x = 22.6  to fill out the following table. x 14 18 22 26 33 x 22.6 22.6 22.6 22.6 22.6 x − x 14 − 22.6 = −8.6 18 − 22.6 = __________ 22 − 22.6 = −0.6 26 − 22.6 = _________ 33 − 22.6 = 10.4 (x − x)2 73.96 __________ 0.36 ________ 108.16

R² is: O The ratio of the variance accounted for by the predicted values of Y to the variance accounted for by the observed values of Y. O The ratio of the variance accounted for by the observed values of Y to the variance accounted for by the predicted values of Y. O The MSR divided by the MS. O The SS, divided by the SSy.
