Step-by-step explanation:
Hello!
We have the information of the average wind speed for three months:
February:
Mean: 2.324
SD: 1.577
Otlier: 6.73 mph
June:
Mean: 0.857
SD: 0.795
Otlier: 3.93 mph
August
Mean: 0.63
SD: 0.597
Outlier: 2.53mph
a)
Z= X - μ ~N(0;1)
δ
[tex]Z_{February}= \frac{6.73 - 2.324}{1.577}[/tex]
[tex]Z_{Februar}= 2.793[/tex] ≅2.79
[tex]Z_{June}= \frac{3.93 - 0.857 }{0.795}[/tex]
[tex]Z_{June}= 3.87[/tex]
[tex]Z_{August}= \frac{2.53 - 0.63}{0.597}[/tex]
[tex]Z_{Augus}= 3.182[/tex] ≅ 3.18
b)
Comparing the three Z-scores you can say that the strongest wind event was in June. The number obtained means that is the furthest one in relation to the mean.
