For the same data (anorexia), I later realized that (a) the general parametric assumptions (normality, homogeneity of variances) were met for a parametric one-way ANOVA; (b) there was a covariate to include in my analysis, participants’ pre-treatment anorexia, Pretest.  I then ran an independent ANCOVA to answer the same question, controlling for pre-treatment level of anorexia.  Some of the results are given below: ANCOVA.pdf 

Think about the three methods of conducting multiple regression (i.e., forced entry, stepwise, & hierarchical), which method was used for the current analysis?

Find all the zeros. f (x) = x3 + 10×2 + 25x + 18

Solve the problem.A model rocket is launched from a raised platform at a speed of 112 feet per second. Its height in feet is given by h(t) = -16t 2 + 112t + 20 (t = seconds after launch). After how many seconds does the object reach its maximum height?

Solve the problem.An on-demand printing company has monthly overhead costs of $900 in rent, $500 in electricity, $100 for phone service, and $160 for advertising and marketing. The printing cost is $40 per thousand pages for paper and ink. The average cost for printing x thousand pages can be represented by the function (x) = .For a given month, if the printing company could print an unlimited number of pages, what value would the average cost per thousand pages approach? What does this mean in the context of the problem?
