Groups of dolphins were systematically observed off the coast of Iceland near Keflavik in 1998. Each observation included the main activity of a dolphin group (Activity) and the time of day the group was observed (Time). The groups varied in size, with feeding or socialising groups usually including more dolphins than travelling groups, but no information about group size was included with the data. The observations are summarised in the following table: No. of groups, summarised by activity and time. Time Morning Noon or Afternoon Evening Activity Travelling 6 20 13 Feeding 28 4 56 Socialising 38 14 10

(a) In looking for an association between Activity and Time, which variable would be the predictor and which the response? Justify your answer.

(Is this correct),My answer is-

1. The predictor variable is the main activity of a dolphin group

         (Activity) and the response variable the time of day the group was

         observed (Time). The Activity of the dolphins decides what time of day

         it is.

(b) How strong is the evidence that dolphin activity typically varies during the day? Test at a 1% significance level.If you conclude that there is a relationship, describe it.

Does this look like I am on the right path?

(My answer)

1. H0: There is no association between Dolphin Activity and the Time of day.

H1: There is some association.

     Significance Level: α= 0.01

         The test requires for the sample to be randomly selected and all the

         expected observations to be ≥5.

(My question)-It says the dolphins are systematically observed(does that mean it is not a random sample?)

Thirty small communities in Connecticut (population near 10,000 each) gave an average of x = 138.5 reported cases of larceny per year. Assume that σ is known to be 44.5 cases per year. (a) Find a 90% confidence interval for the population mean annual number of reported larceny cases in such communities. What is the margin of error? (Round your answers to one decimal place.)

(b) Find a 95% confidence interval for the population mean annual number of reported larceny cases in such communities. What is the margin of error? (Round your answers to one decimal place.)

(c) Find a 99% confidence interval for the population mean annual number of reported larceny cases in such communities. What is the margin of error? (Round your answers to one decimal place.)

(d) Compare the margins of error for parts (a) through (c). As the confidence levels increase, do the margins of error increase?

As the confidence level increases, the margin of error decreases. As the confidence level increases, the margin of error increases.     As the confidence level increases, the margin of error remains the same.

(e) Compare the lengths of the confidence intervals for parts (a) through (c). As the confidence levels increase, do the confidence intervals increase in length?

As the confidence level increases, the confidence interval remains the same length. As the confidence level increases, the confidence interval decreases in length.     As the confidence level increases, the confidence interval increases in length.

Wal-Mart Predatory Pricing Case At issue was whether Wal-Mart, which had built the nation’s largest retail chain with its everyday-low-price strategy, went beyond the legally recognized retail practice of promotional pricing and intended to destroy its competition. A 1993 lawsuit filed against Wal-Mart by a group of independent pharmacies argued that Wal-Mart used predatory pricing. The Arkansas statutes, which were being tested for the first time since passage in 1937, generally forbade businesses from selling or advertising ‘any article or product … at less than the cost to the vendor … for the purpose of injuring competitors and destroying completion.’ Wal-Mart’s attorneys argued in a pretrial brief that what the law described as a ‘product’ shouldn’t be considered to apply to individual items, but rather to Wal-Mart’s ‘market basket’ or full line of products. If the entire line isn’t priced below cost, they contended it wasn’t a violation of the statute. It is obvious that in order to determine a state violation on ‘predatory pricing,’ the court must determine what principle it would accept as ‘nonpredatory’ in pricing below cost. This is indeed a gray area. The second element to be considered under state laws is whether there was an ‘intent’ to injure competition and whether in fact the result of such malice was to injure the competition. The third element was ‘recoupment.’ Were the prices ultimately raised, once the competition was put out of business?

What is predatory pricing?

Why would it matter if prices were ultimately raised once the competition was out of business?”

4.If a student is observed dropping a course from her Fall Quarter schedule, an economist is most likely to conclude that:

a.the course was the last additional course for which the marginal benefit was positive.

b.the marginal benefit of dropping that course must be greater than the marginal cost.

c.the additional cost in tuition and study time must be less than the additional benefit of that particular course..

The council wants to construct the facilities that will maximize expected daily usage by the residents of the community subject to land and cost llimitations. The usage, cost, and land data for each facility are listed below. The community has $240,000 construction budget and 24 arces of land. Because the swimming pool and tennis center must be built on the same part ot the land parcel, however, only one of these two facilities can be constructed. Formulate an optimization mode to assist the council in making its decision. Q1) Define the decision variables for this problem. What type of vaiables must beused in this situation? Q2) Write out the objective function for this problem in terms of the decision variables defined above. Q3?Write out any constraints necessary for this problem in terms of the decision variables defined above. Q4) A very inluential citizens group has made it clear that it strongly prefers the athletic fielld to the gynnasim; thus the council will not approve the gymnasium unless the athletic field is also approved. How can the model be modified to incorporate this condition? Q5) The mayor has deicded that no more than three of the facilities may be constructed wiht funds from this year's budget. How can the model be modified to incorporate this comdition?
