Il. Identify the population and the sample: 1. A survey of 1500 Filipino households found that 48% of the households own a computer. Population: Sample: 2. A recent survey of 5325 elementary school children found that 28% of the children could be classified obese. Population: Sample: 3. The average weight of every sixth person entering the mall within a 3-hour period was 56 kilos. Population: Sample: Ill. Identify the parameter and statistic in the following:C. X = 19 7 = d. X = 3.78 7= e. X = 6.5 7= 2. A normal distribution of scores has a standard deviation of 15. Find the z-scores corresponding to each of the following values: a) A score of 90, where the mean score of the sample data values is 45. Z= b) A score of 75, where the mean score of the sample data values is 35. Z= c) A score of 40, where the mean score of the sample data values is 28, Z=Activity 2 Standard Score or z-Score I. Convert the following to a Z-score, round off your answer to two decimal places. 1. The following scores were obtained as part of a sample with a mean of 11 and a standard deviation of 2.3. For each score, find the appropriate z-score: a. X = 23 Z = b. X = 17 Z = C. X = 19 Z = d. X = 3.78 Z = e. X = 6.5 Z = 2. A normal distribution of scores has a standard deviation of 15. Find the z-scores corresponding to each of the following values: a) A score of 90, where the mean score of the sample data values is 45.Activity 1 Sampling Theory (Population and Sample, Parameter and Statistic) I. Determine whether the data set is a population or a sample. * 1. The age of each provincial governor in the Philippines. * 2. The speed of every fifth car passing a police speed trap. 3. The annual salary for each employee at a company. * 4. A group of patients in a hospital who are given a particular treatment. 5. The list of all the world leaders. Il. Identify the population and the sample: 1. A survey of 1500 Filipino households found that 48% of the households own a computer. Population:\fActivity 1 Areas Under Normal Curve I. Find the area under the standard normal curve. 1. z = 2.28 P(z S 2.28) = P(z 2 2.28) = 2. z = -2.05 P(2 S-2.05) = P(z 2 -2.05) = 3. Z = 0.28 P(z S 0.28) = P(z 2.28) = 4. P(0
