Consider the differential equation $$(1+x^2)y' - 2x(y+1) = 0.$$ This DE is in fact both separable and linear. (a) Show that the DE is separable by writing it in the form (1.9), and solve it using the techniques in section 1.2 of the course notes. (b) Show that the DE is also linear by writing it in the form (1.20), and solve it using the techniques in section 1.4 of the course notes. Do your answers match? In each case, make sure you carefully show all of the steps involved in the process of solving the differential equation.

Voice-Over-Internet-Protocol (VOIP). Will it have a significant impact on the true mean monthly cell phone bill? The historical mean has been $64.58 per customer. n = 20 customers with VOIP connections, x bar = 58.6324, s = 12.1347. Does VOIP significantly lower the mean monthly cell phone bill? Test at the 0.05 level; assume the population is approximately normal. Show all steps. Use R to find tcalc, tcrit, and the p-value. Create the decision criteria matrix in R (provide R code output in console) What proportion of cell phone customers expect to get VOIP in the next 6 months? If the true proportion is greater than 1/3, a marketing campaign will be undertaken to recapture the customers. A random sample of n = 60 customers had 31 of them that expect to get VOIP. Test at the 0.01 level, show all steps. Use R to find zcalc, zcrit, and the p-value. Create the decision criteria matrix in R (provide R code output in console) Assess the practical significance of the results of the hypothesis tests.
