You have been assigned by your company, “Progress ‘R Us” to study if there has been a decline in recent years of Adult Chinook salmon at the McNary Dam and if there is a mortality rate of this species between The Dalles Dam and the McNary Dam. <\/p>\n

You have the following raw data to work with (from HERELinks to an external site.<\/span><\/span><\/a>) — the data are actual fish counts at the Dam. <\/p>\n

Using this data answer the questions that are posed below the data table.<\/p>\n

These tools will be needed:<\/p>\n

1. Download the Chart Tool <\/a>
2. Use this tool to determine means and standard deviationsLinks to an external site.<\/span><\/span><\/a><\/h4>\n

3. Use the Z-test Calculator<\/a> when needed<\/p>\n

a) Enter the data into the chart tool (you can minimize typing by just entering the data in units of thousands so instead of entering 312700 just enter 312 or 313 if you want to round up). Include your chart in your homework submission and comment on the ensuing pattern of the data that you notice. <\/p>\n
b) Compute the means and standard deviations over the entire data period (1957-2014) and use the Z-test to show that the Counts at McNary Dam are significantly lower than at the Dalles Dam. <\/p>\n
c) For just the Dalles Dam counts: Compute the average and standard deviation of the counts between the period 2001- 2014 and from 1957-1999. Use the Z-test to determine if there is a significant difference between these two time periods. <\/p>\n
d)From the result you just got above, what does this tell you about the relation between dams and decreasing salmon in the Columbia River system. Offer a data informed opinion and not your personal opinion. <\/p>\n
e) Compared to the 2001-2014 period (again Dalles Dam) are the low counts observed in 2007 statistically significant? If so, what factors in that year do you think might have caused this (temporary) decline (do some research to support your statements)<\/h4>\n
