31. 5 is subtracted from each observation of a set, then the mean of the
observation is reduced by
32. The standard deviation of 10 observations is 15. If 5 is added to each observations the value of new standard deviation is a) 5 b) 1 c) 0 d) 15 33. If the minimum value in a set is 9 and range is 57, the maximum value of
the set is 34. Which of the following situations exhibit the function of inferential
statistics? 35. Which of the following situations exhibit the function of descriptive
statistics? For items 36 to 39, consider this situation. There were 200 students of PUP
San Juan enrolled in General Statistics in the first semester. A periodic examination was given and it was found out that the average score is 93. When a random section with 50 students is chosen, it was found out that 89 is the average score of the section. 36. What do we call to the number 200? a) Statistics b) Sample size c) Parameter d) Population size 37. What do we call the number 93?
38. What do we call number 50?
39. What do we call number 89?
For items 40-42, consider this situation. A group of undergraduate researchers aims to execute stratified random sampling among 63 section 1 student, 52 section 2 students, 48 section 3 students and 37 section 4 students. The margin of error is 5%.
