Isle Royale, an island in Lake Superior, has provided an important study site of wolves and their prey. Of special interest is the study of the number of moose killed by wolves. In the period from 1958 to 1974, there were 296 moose deaths identified as wolf kills. The age distribution of the kills is as follows. Age of Moose in Years Number Killed by Wolves Calf (0.5 yr) 1-5 6-10 11-15 16-20 114 54 74 49 5 (a) For each age group, compute the probability that a moose in that age group is killed by a wolf. (Round your answers to three decimal places.) 0.5       1-5       6-10       11-15       16-20       (b) Consider all ages in a class equal to the class midpoint.

The article cited in Exercise 4 also investigated the effects of the factors on glucose consumption (in g/L). A single measurement is provided for each combination of factors (in the article, there was some replication). The results are presented in the following table. Glucose Consumption 68.0 -1 -1 -1 -1 -1 77.5 -1 -1 98.0 1. 1. -1 98.0 -1 -1 74.0 -1 77.0 -1 97.0 98.0 Compute estimates of the main effects and the interactions. a. Is it possible to compute an error sum of squares? Explain. Are any of the interactions among the larger effects? If so, which ones? d. Assume that it is known from past experience that the additive model holds. Add the sums of squares for the interactions, and use that result in place of an error sum of squares to test the hypotheses that the main effects are equal to 0. Ъ. C.

Suppose the doctors at a local office take a health survey of 100 adult female patients with similar weight who have had appointments in the last week. According to their medical file, the 100 participants all weigh between 140 – 149 lbs. One of the survey questions asks participants to list their current weight. The accompanying tables show the relative frequency of weights measured by the physician for the 100 participants and the relative frequency of weights recorded in the survey for the 100 participants. Note that some of the weights reported in the survey did not fall between 140 – 149 lbs. Weights reported by physician (to the nearest pound) Weights recorded by participants Weight (in pounds) Relative frequency Weight (in pounds) Relative frequency 140 0.12 140 0.32 141 0.09 141 0.04 142 0.17 142 0.05 143 0.06 143 0.04 144 0.14 144 0.07 145 0.11 145 0.23 146 0.04 146 0.01 147 0.10 147 0.01 148 0.09 148 0.03 149 0.08 149 0.02 Total 1.00 Total 0.82 Select the statements that are…

The scientific productivity of major world cities was the subject of a recent study. The study determined the number of scientific papers published between 1994 and 1997 by researchers from each of the 20 world cities, and is shown below.   City Number of papers City Number of papers City 1 99 City 11 66 City 2 2020 City 12 44 City 3 2929 City 13 1313 City 4 3030 City 14 2929 City 5 2828 City 15 77 City 6 3030 City 16 1616 City 7 2727 City 17 2727 City 8 99 City 18 1515 City 9 2626 City 19 2929 City 10 2020 City 20 2727 Construct a 9090 % confidence interval for the average number of papers published in major world cities.  <μ<<μ<

Anthropologists can estimate the birthrate of an ancient society by studying the age distribution of skeletons found in ancient cemeteries. The numbers of skeletons found at two such sites, as reported in the article "Paleoanthropological Traces of a Neolithic Demographic Transition" (J. Bocquet-Appel, Current Anthropology, 2002:637– 650) are given in the following table: Ages of Skeletons 0-4 years 5-19 years 20 years or more Site Casa da Moura 27 61 126 Wandersleben 38 60 118 Do these data provide convincing evidence that the age distributions differ between the two sites?
