In the last chapter, we looked at three outliers arising from a plot of Average Wind Speed by Month in the Hopkins Forest. Each

Aloiza [94]

Answer:

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

Z= X - μ ~N(0;1)

$Z_{February}= \frac{6.73 - 2.324}{1.577}$

$Z_{Februar}= 2.793$ ≅2.79

$Z_{June}= \frac{3.93 - 0.857 }{0.795}$

$Z_{June}= 3.87$

$Z_{August}= \frac{2.53 - 0.63}{0.597}$

$Z_{Augus}= 3.182$ ≅ 3.18

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.
