Note that there's a strict order here -> 2 close friends, then 1 non-close friend.

So, picking in order:
probability of picking the first close friend: 4/10
probability of picking the second close friend: 3/9
probability of picking the first non-close friend: 6/8

So, we get 4/10 * 3/9 * 6/8 = 1/10.

Which answer is the best estimate of the correlation coefficient for the variables in the scatterplot?
Yuri [45]
-0.8 would be the best estimate.

The data seem to have a negative correlation, since they are decreasing; this means our r-value will be negative.

Our two negative choices are -0.25 and -0.8.  -0.8 would be a fairly strong correlation, whereas -0.25 would be a weak correlation.  The data do seem to be fairly strongly related, so we will use -0.8.
