Solve the following problem.

1. A researcher plans to get an appropriate number of sample for his research in political science from 3,000 students. Compute the sample size using 5% margin of error.

2. Group of SHS students is conducting research for their final paper. There are 2,300 students in Grade 11 as target respondent, however due to time and resources, their adviser suggested getting a sample at 10% margin of error. Compute the required sample size.

Sampling and Sampling Distribution A. ENGAGE Let's practice the process that you did in our lesson by answering the exercises below General Instruction: Solve the following problem

1. Consider the set of even single-digit number {0, 2, 4, 6, 8}. a.Make a list of possible sample size of 2 that can be taken from this sets of numbers b.Construct the sampling distribution of the sample means for the size of 3 and the standard error.

2. In the numbers {1, 3, 5, 7, 9} construct the following: a. List of possible sample size of 3 that can be taken from this sets of numbers b. Sampling distribution of the sample means for the size of 3 and the standard error.

B. EVALUATE

1. A sample size of 36 is to be selected from a population that has a mean of = 45 and standard deviation of 10. a. Find the mean of the sampling distribution b. Find the standard error of the sampling distribution. c. What is the probability that this sample mean will be between 40 and 50?

2. The height of grade 1 pupils are approximately normally distributed with = 45 inches and = 2. a. If an individual pupil is selected at random, what is the probability that he or she has a height of 42 and 47? b. A class of 30 of these pupils is used as a sample. What is the probability that the class mean is between 42 and 47? c. If a pupil is selected at random, what is the probability that is taller than 46 inches? d. A class of 30 of these pupils is used as sample. What is the probability that the class mean is greater than 46 inches
