Consider a numerical example using the Solow growth model: The production technology is Y=F(K,N)=K0.5N0.5 and people consume after saving a proportion of income, C=(1-s)Y. The capital per worker, k=K/N, evolves by (1+n)k’=szf(k)+(1-d)k. (a) Describe the steady state k* as a function of other variables. (b) Suppose that there are two countries with the same steady state capital per worker k* and zero growth rate of population(n=0), but differ by saving rate, s and depreciation rate, d. So we assume that...

T F 1. A p-value of .008 in hypothesis testing means there is only a .8% chance we could get such sample statistics from the population if the null hypothesis is as stated. Such an event is considered unlikely and we would reject the null hypothesis. T F 2. As a general rule in hypothesis testing, it is always safer to set up your alternate hypothesis with a greater-than or less-than orientation. _____3. If the level of significance is .02...
