Question
Statistics is a Science of: Finding answers based on Guesses and conjectures not backed by proof Exact calculations that can only be based on specific elements regardless of any trend Decisions making based on collection analyzing and drawing conclusion based on data. Using representations that are only designed to mislead studies The entire collection of objects or outcomes about which data are collected is called: Variable Experiment Sample Population Variability of a set of data is studied because: to prove data collection always yields optimum and flawless results Successive observations of a system do not always produce exactly the same results Because of certainty of the methodology used to show that all data collection methods ultimately are good and result producing Which of the followings CAN NOT be a randomly selected sample: Use of the random generator in any given computer Picking every 5 member of the population Throwing the names of the members in a hat and picking one Picking a piece of candy from a mixed bag with eye fold on In a study of chemical reaction the chemist periodically adds different but allowable chemicals to observe reactions, This is a process of: Observational study Random sampling designed experiment multiple sampling Members of a population are created for a certain specific study, This population is considered to be: Conceptual population physical population virtual Population sample of the populationExplanation / Answer
11). C is answer-
Statics is a decision making based on the collection analyzing and drawing conclusion based on the data.
12)-D is the answer
The the entire collection of the objects or outcomes about which data are collected called - Population
because it is saying entire collection , entire full collection only a population , sample is the part of population so it can not be entire collection.
Variable is the type of data
experiment is event . so only answer is Population
13)B answer
because Variabilty is that the variation in the data , how much variation in the data,
even a single process can not generate exatly the same results
to know the system or process well , variabilty is studied .
14)B answer
B is because selecting every 5th member of population is not a ramdom event becuase we have fixed the event and every 5th member can not give the accurate information about the population . so it will not a randomly selected sample.
15)C
it is a designed experment , beacuse it is stted that amount is fixed .
16)C
sample of population .
