Instruction: Read and analyze the following situations and supply the values of the following variables (if there is any). On the third column, write known on the space provided if the situation gives or can compute the value of the variance, otherwise write unknown. Identify also the formula to be used to estimate the standard error of the mean by writing the symbols og, when the population variance is known and Sg when the population variance is unknown. Situation Given Answer Standard error formula 1. Consider population N= n = a consisting of 1, 2, 3, 4, 5, 8, 9, and 11. Samples of size 3 drawn are from this population. 2. Given the population mean sample n = of 12, standard deviation of 3 in a and a u = sample size of 125 S = 3. A population composed of N = n =_, 11 items whose measurements are 12, 7, 9,11,8, 20, 23, 18, 13, 22, and 10. Samples of 5 items drawn are at random without replacement.
