The Austin Blind Salamander, Eurycea waterlooensis, has only one habitat: Barton Springs. Scientists wanted to investigate the impact of humans on the salamander, so they counted the number of salamanders in various 10-cubic-meter plots of water 1km upstream and 1km downstream of Barton Springs pool. Below are their results:

Upstream 12, 14, 17, 22, 18, 10, 15, 19, 11, 20

Downstream 9, 8, 5, 12, 13, 7, 3, 16

Assuming their data was from a random sample with independent observations, conduct the appropriate hypothesis test to determine if there is a difference in the number of salamanders upstream from Barton Springs compared to downstream. Include all steps for full credit. Given: critical value = 63 (5pt)
