Name: Score: Year and Section: Teacher: EXERCISES 1. Tell whether the following value Is a statistic or a parameter, 1.) The Mathematics teacher randomly selected 25 questions from the previous examination to be given in the Chapter test. 2.) The ABM faculty consists of 5 male teachers and 3 female teachers. 3.) The Window Corporation has 278 employees. 4.) The supervisor randomly selected 9 employees to participate in the seminar. 5.) It was found out that 12 students in a certain school have high IQs. I1. The following are the scores in Statistics of randomly selected Grade 9 students in their First Quarter Examination. 94 93 78 87 82 95 89 88 87 Compute the following: a. Sample Mean b. Sample Variance c. Sample Standard Deviation Ill. The following are the heights in centimeters of the members of the basketball varsity team i Gold Warriors. 185 170 170 168 172 169 171 180 179 175 Compute the following: a. Population Mean b. Population Variance c. Population Standard Deviation 43Name: Score: Year and Section: Teacher: EXERCISES 1 in a given normal distribution, the sample mean is 90 and the sample standard deviation is 8. Find the corresponding standard score of the following values 1.) 85 2.) 82 3.) 100 it. In a given normal distribution, the population mean is 75 and the population standard deviation is 5. Find the corresponding standard score of the following values. 1.) 85 2.) 73 3.) 65 Ill. Solve the following problems. Draw the curve. Show all the solutions. 1.) On a final examination in Statistics, the mean was 80 and the standard deviation was 8. Determine the standard score of a student who received a score of 95 assuming the scores are normally distributed. Result: SE Standard score: 2.) Consider the normal distribution of IQ's with a mean of 125 and a standard deviation of 20. What percentage of IQ's are, a.) greater than 90 Mean: Standard Deviation: Result: Standard Score: Percentage: 35
