Complete the following statements by writing the correct word or words and formulas. 1. The likelihood measure of the confidence interval that is represented by a percentage that refers to all possible samples that can be estimated to contain the true population parameter is called 2. Confidence coefficient or is expressed as zo. 3. A range of values that is used to estimate a parameter is known as 4. n is the symbol used for the 5. To compute the length of confidence interval given the standard deviation, there are two formulas to consider. These are: and 6. To compute for the sample size, the formula to be used are and 7. Complete the Level of Confidence and z. Table on the second row. Confidence 99% 98% 96% 95% 92% 90% 85% 80% 70% Level Ze 2.58 2.05 1.75 1.44 1.04Read the following problem carefully. Apply your skills in solving the following case. A researcher found that the IQ scores of the ALS students in the Division of Tagum are normally distributed with a mean of 110 and a standard deviation of 10. 1. How many ALS students are needed to test so that the estimate will not be more than 5 from the population mean with a 99% level of confidence? (Show your solution on a separate sheet of paper) 2. Due to limited contact with ALS students, the researcher tested a small number of ALS students. Explain the effect of this small sample on the estimate of the parameter
