Defining the sampling Lesson Distribution of the Sample 7 Mean using the Central Limit Theorem What's More Activity. Solve and Describe The scores of individual students on a national achievement test have a normal distribution with mean 20.8 and a standard deviation of 1.9. At Feliciano Delos Santos High School, 84 students took the test. If the scores of the students at this school have the same distribution as the national scores, how will you describe the sampling distribution of the scores of these students? Assume that the population is infinite. Step 1. Identify the given information. Step 2. Determine the mean of the sampling distribution. Use the property that HX = H Step 3. Solve the standard deviation of the sampling distribution. Use the property that Ox = in 16SAMPLING DISTRIBUTION OF Lesson THE SAMPLE MEANS FROM 5 AN INFINITE POPULATION What Can I Do Activity ( Describe Me) The heights of OSHS male students in your school are normally distributed with a mean of 156 cm and standard deviation of 10 cm. Describe the sampling destribution of 20 students who are randomly drawn from this population. Solutions: Steps Solutions 1 . 2. An 3. 2 . 4. 3 . Conclusion: 14Lesson THE CENTRAL LIMIT 6 THEOREM What's New Activity 1. ( Do It Yourself ) Get a die. Roll it 50 times. Record the result of your experiment in a table. The first table is for rolling a die once in 50 times, the second table is for rolling a die twice in 50 times, and the 3'd table is for rolling a die thrice in 50 times.Show the result of your experiment to your teacher. 1 st roll 2nd roll 3rd roll Mean 1 st roll 2nd roll mean 1 st roll 2 1 2 3 2 3 3 4 5 4 5 6 5 6 7 7 8 8 9 8 10 9 9 10 10 50 50 50 On a separate sheet of paper, 1. Make a histogram of the distribution of rolling a die once in 50 times. What can you say about the resulting histogram? Answer: 2. Make a histogram of the means of rolling a die twice in 50 times and rolling a die thrice in 50 times. Answer: 3. What can you say about the three histograms? Draw out a conclusion out of the three histograms. Answer: 15
