Decide whether this table could represent a proportional relationship. If the relationship could be proportional, what would be
the constant of proportionality?
The distance from which a lighthouse is visible:

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

Given sin28.4=.4756, cos28.4=.8796, and tan28.4=.5407 find the cos of 61.6

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) ).
