Helena builds a shed in her backyard. There is a larger
section for large tools, like her lawn mower,
and a smaller section for small tools. What is
the length of the entire shed? What type of
number is the length? List as many types of
numbers for the length as you can

What are two numbers that have a sum of 15?

What is the value of x? assume that the line is tangent to the circle.

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) ).
