What conclusion can be derived by comparing the central tendencies of the two data sets?
a: {7, 6.3, 1.6,2,4,6,3,5}
b: {2, 2, 2, 3, 4, 5, 2, 8, 7, 6}

See below.

Step-by-step explanation:

The mean of set A = 4.3625

The mean of set B  = 4.1.

The means are very close.

The median of set A = 4.5

The median of set B = 3.5.

The mean and median of Set A are quite close so we can say that the data is  close to Symmetrical.

In the case of set B the mean and median are further apart so the data is more skewed . it is skewed towards the  lower values  (to the left).

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
