The four terrestrial planets, Mercury, Venus, Earth, and Mars, are all much closer together compared to the distances separating the outer planets (anything beyond mars)

The 99% Confidence Interval is:

−3.72≤3.2≤<span>10.12
</span>Since 0 is included in this interval, these results suggest that a difference of 3.2 could have resulted from mere random variation.

<span> Note that we divided (1-.99) by 2 because we are interested in the two-tailed confidence interval.
We can validate our results using the confidence interval for mean calculator</span>
No I think because snails need to use water to breath.
Answer:
Narrow bands of strong wind that generally blow from west to east all across the globe.
