I need help, thank u.

4. Which concept of random sampling distribution of the sample means using Central Limit Theorem? a. If you have a population mean u and standard deviation o and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately distributed normally. b. The probability of the simultaneous occurrence of two events that are independent is given by the product of their individual probabilities. c. If you have a population mean u and standard deviation o and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately distributed same as the original population. d. The larger the sample size n in sampling distribution of sample mean, the lesser the histogram is to show the normalcy of the distribution. 5. How do you compare the formula Z == *-H from = _ 2 a. Both can be used alternatively. b. Former is used when solving Z from original population while the latter is used in random sample. c. Former is used when solving Z from random sample while the latter is used in original population. d. Former is used in random sample and original population but the latter can only be used for random sample. 6. What is the estimate, if sample size of random sampling using Central Limit Theorem is almost normal in accordance to Statisticians? a. Ifn= 2 c. If n= 10 b. In= 3 d. If n= 30 7. Solve for the sample mean for the sample S=(2, 3, 4.5, 6, 8.5) a. 5 c. 6 b. 4.8 d. 6.8 8. Using the table below, solve for the g = N Observation x X - M (x - 1/2 P ( X = x) 1 1 -1.5 2.25 2 2 -0.5 0.25 3 3 0.5 0.25 4 1.5 2.25 Ex = 10 E(x - 1)2 - 5.00 EP (X = x) = 1 a. 1.12 b. 1.25 c. 1.5 d. 1.85 O
