On the following pages you are presented with five problems. Your job is to examine the output and discuss whether there is a statistically significant relationship between the two variables, the pattern or direction of the relationship if the relationship is significant, and the strength of the relationship if the relationship is significant. AS you discuss the strength of the relationship, you will rely on an appropriate measure of association from those that have been given. For that determination, you will need to appropriately determine the level of measurement of each of the variables being examined. Please use the Measures of Association Chart I provided to help you with your determination. You may write your responses on a separate document or next to the problems on this one.
To count whale populations, the "capture" is done by means of a photograph, and the "tagging" is done by identifying each each captured whale through their unique individual pigmentation and markings. To estimate the population of gray whales in a region of the Pacific between Northern California and Southeast Alaska, 121 gray whales were "captured" and "tagged" in 2007. In 2008, 172 whales were "recaptured". Of these, 76 had been "tagged" in the 2007 survey. Based on these figures, estimate the population of gray whales in the region. There were approximately Answer gray whales in the region.
