denis-greek [22]

Answer:

\bullet \ \large\text{The mean in period 2 is higher than the mean in period 1.}

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”.
