Performance Task Instruction: Determine whether the following statements has a known or unknown population variance and write your answer on the second column. Identify also the formula to be used to estimate the standard error of the mean by writing the symbol ox, when the population variance is known and the symbol Sz when the population variance is unknown. Situation Answer Standard Error Formula 1. Hereza Start is an enrichment program for Grade 11 SHS students. The program's heads would like to know the mean intelligence (IQ) of its participants. They know that IQ has standard deviation of 15 points. They take a random sample of 20 students and administer IQ tests. These are the scores:98, 82, 100, 102, 78, 79, 95, 89, 90, 99, 105, 103, 93, 99, 101, 89, 102, 76, 91, 100. 2. Given the following values: X 110, s = 6, n = 16, u = 102, and o = 7 3. Joel administered a mathematics achievement test to a random sample of 40 Grade 10 students. In this sample, he obtained the mean and variance to 89 and 81 respectively. The population mean is 85.
