Jkins University 14. Imagine three different normally distributed populations Mus. 0"), Mus.o'), and N(co"). All three has the same unknown variances. From each population, you have taken a sample of size 5. These samples are given in the following table: Three samples; each of size n = 5 ABC 16 33 23 18 31 27 19 37 21 17 29 28 13 34 25 (a) How many different points estimators for of can you suggest? Calculate value of these estimators. (b) If you assume that HA = UB = /c, how would your estimation of of would change
