LESSON 5: SUMMATIVE TEST IN STATISTICS Compute the mean (ux) variance (ax) and standard deviation (ox) of each sampling distribution. 1. When 100 independent samples are taken X 5 fix) 1/12 1/12 2. When 4 independent samples are taken X 3 f(x ) 1/5 1/5 1/5 1/5 1/5 3. When 25 samples are drawn with replacement 3 Ply) 1/2 1/6 1/3 4. When 64 samples are drawn with replacement 3 F (2) 0.6 0.1 0.2 0. 1 5, When 36 samples are drawn with replacement 10 20 F (1) 3/7 4/7 6, A random sample of size 30 taken from a population of 1000 with #=20 and a*=9. 7, A random sample of size 80 taken from a population of 10000 with #=46.5 and a*=16. 8. A random sample of size 45 taken from a population of 900, with #=18.25 and -81. 9. A random sample of size 64 taken from a population of 1200 whose # =72.12 and a= 12. 10. A random sample of size 36 taken from a population of 3200 whose # = 28.6 and a= 54.4
