The formula for the standard deviation of a sample is: s equals square root of fraction numerator 1 over denominator n minus 1 end fraction sum from i equals 1 to n of (X subscript i minus X with bar on top )squared end root Select the true statement for the following data set that has a mean of
9, 3, 7, 8, 8, 8, 9, 10, 10, 13, 14

there are no figures how am i supposed to answer this question

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
