Question

In order to conduct a study of resistivity on a certain semiconductor wafers, a sample was taken from a supply of semiconductors kept at a storage facility. The items kept at the storage is considered to be the: Conceptual population physical population virtual Population manufactured population Which of the followings Is on appropriate measure of the variability of a sample Mean Median Standard Deviation sample size As a quality assurance attempt in a manufacturing setting, every fifth Item Is picked for further testing till a sample of 50 is attained. This type of sampling is called: Convenience Random systematic stratified at of 3000 thermometers manufactured by a thermometer manufacturing firm in one week 400 are reading the freezing point between "0" degrees and "-5" degrees. Out of the 400 thermometers 150 of read the freezing points below "-5" degrees. 150 is considered to be: Parameter Statistic Variable Population Given the following set of test score with their respective frequencies, what Is the relative frequency associated with the score 80.

Explanation / Answer

17) option B

18)option C

19)option C

20option B

21) total frequency=5+8+7+5+6+2+1=34

hence relative frequency=5/34 ~15%

option B
