Answer:
Order the set of values
9, 10, 11, 12, 14, 20
<h2>Median:</h2>
Middle Value
n = number of values
if n is odd, the median is at position n/2
if n is even, the median is between position n/2 and n/2 + 1
n = 6
6 is even, so the median is between position 6/2 and 6/2 + 1
the median is between 11 and 12
(11 + 12)/2
23/2
11.5
<h2>Mean </h2>
9 + 10 + 11 + 12 + 14 + 20 = 76/6
= 12.666...
= 12.7 to the nearest tenth.
