The article cited in Exercise 4 also investigated the effects of the factors on glucoseconsumption (in g/L). A single measurement is provided for each combination of factors (inthe article, there was some replication). The results are presented in the following table.Glucose Consumption68.0-1-1-1-1-177.5-1-198.01.1.-198.0-1-174.0-177.0-197.098.0Compute 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 thesums of squares for the interactions, and use that result in place of an error sum ofsquares to test the hypotheses that the main effects are equal to 0.Ъ.C.

A special education teacher did research on whether or not there is a relationship between the number of students in his class and the number incidents of “acting out” behaviors exhibited by the autistic students in the classroom. He collects data for a year and aggregates them by month. He obtained the statistics below, r= -.863 R2=.74 b= -1.212294 a= 131.176598 10.) How does the presence of more students affect the incidents in the class? a) as students are added the incidences increase b) as students are added the incidences decrease c) the number of students does not affect acting out d) the number of students caused more incidents How much of the variability of acting out is explained by the number of students in the class?___________

Bighorn sheep are beautiful wild animals found throughout the western United States. Let x be the age of a bighorn sheep (in years), and let y be the mortality rate (percent that die) for this age group. For example, x = 1, y = 14 means that 14% of the bighorn sheep between 1 and 2 years old died. A random sample of Arizona bighorn sheep gave the following information: x 1 2 3 4 5 y 15.8 17.3 14.4 19.6 20.0 Σx = 15; Σy = 87.1; Σx2 = 55; Σy2 = 1,540.45; Σxy = 272 (a) Find x, y, b, and the equation of the least-squares line.
