On your TI-83, you enter a set ofx-values in list L4 and a set of y-values in list L6. The regression equation is stored in Y1. You move the cursor on top of L5 and write

a formula that will produce the set of residuals for the ordered pairs (X, Y). That

formula is:

L6-L4

L4 â€" Y1(L6)

Y1(L4) - Y1(16)

L6 - Y1(L4)

Y1(L6) â€" Y1(L4)

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.
