Dada a progressão aritmética -2,3,8,1,3,1,8,23... e a função afim f(x)= 3x - 1. a) Determine a razão dessa progressão aritmética.

b) verefique se para x = {-2,3,8,13,18,23}, tbm obteremos uma progressão aritmética (PA). Utilize a função acima para determinar a nova sequencia numérica.

c) Determine a nova razão dessa progressão aritmética (PA). ME AJUDE PFV​

Consider the linear model for a two-stage nested design with b nested in a as given below. yijk=\small \mu + \small \taui + \small \betaj(i) + \small \varepsilon(ij)k , for i=1,; j= ; k=1, assumption: \small \varepsilon(ij)k ~ iid n (0, \small \sigma2) ; \small \taui ~ iid n(0, \small \sigmat2 ); \tiny \sum_{j=1}^{b} \small \betaj(i) =0; \small \varepsilon(ij)k and \small \taui are independent. using only the given information, derive the least square estimator of \small \betaj(i) using the appropriate constraints (sum to zero constraints) and derive e(msb(a) ).
