Answer:
[24, -12, 6, 42, 18, 0]
Step-by-step explanation:
Multiply each term in this 1 by 6 row matrix by 6:
[24, -12, 6, 42, 18, 0]
First one is 6*5*4*3*2*4*3*2
second is 5*4*3*2*2
Answer:

Step-by-step explanation:
<u><em>the mean in period</em></u> 1 :
(2.3+2.1+2.2+2.2+2.2+2.1+2.4+2.5+2.2+2.0+1.9+1.9+2.1+2.2+2.3)÷15=21.733...
<u><em>the mean in period</em></u> 2 :
(2.3+2.1+3.3+1.5+3.6+1.6+3.0+1.1+4.7+2.1+2.4+1.9+2.8+0.5+2.3)÷15=23.466...
Since 23.466 > 21.733 then “The mean in period 2 is higher than the mean in period 1”.
