1.) Based upon the data, is it reasonable to assume Bigfoot was heading in a relatively straight line? If so, are there any reported locations that seem out of place? What possible reasons could explain these out of place sightings? (List at least two.) 2.) If we assume our large-footed friend was traveling linearly across campus, create a linear model that you feel best fits Bigfoot’s path. 3.) Are there any locations that your model estimates for Bigfoot’s position that would be realistically impossible or highly unlikely? If so, give an example of such a location and explain why it is unlikely. 4.) On the map, there are train tracks running straight and next to the university bike trail. Find the equation of the line that traces over these tracks. Use this equation along with your model of Bigfoot’s path to algebraically estimate the most likely area where Bigfoot crossed the train tracks. 5.) Authorities out to catch Bigfoot, are…

An article discusses the different roles taken by lionesses as they attack and capture prey. The authors were interested in the effect of the position in line as stalking occurs. An individual lioness may be in the center of the line or on the wing (end of the line) as they advance toward their prey. In addition to position, the role of the lioness was also considered. A lioness could initiate a chase (be the first one to charge the prey), or she could participate and join the chase after it has been initiated. Data from the article are summarized in the accompanying table. Position Center Wing Initiate Chase Participate in Chase 28 Role 69 O Ho: Position and role are not independent. H₂: Position and role are independent. 49 (a) Is there evidence of an association between position and role? Test the relevant hypotheses using a = 0.01. State the null and alternative hypotheses. O Ho: Role category proportions are not all the same for lionesses who are in the center of the line or on…
A battery for an electric vehicle will provide a range of 5 miles for each battery, but for each battery the range of all the batteries is decreased by 0.3 miles because of the added weight. a) If it wasn’t for this decrease due to weight, the relationship between range and number of batteries would be linear. Write the formula for this linear relationship. b) now modify the linear case to the non-linear case and write the formula for range in terms of the number of batteries that includes the decrease due to weight. c) Find the maximum range for this vehicle design and the number of batteries that gives the maximum range.
