Consider a completely randomized design with observations on three treatments (coded 1, 2, 3). For the one-way analysis of variance model (3.3.1), p. 33, determine which of the following are estimable. For those that are estimable, state the least squares estimator. a) τ1 + τ2 − 2τ3.
b) μ + τ3.
c) τ1 − τ2 − τ3.
d) μ + (τ1 + τ2 + τ3)/3.
the model is
Yit = μ + τi + Eit
Eit N (0,02),
Eii's are mutually independent,
t = 1,, ri i = 1,, u
Yit N(μ + τt, 02)

What is the ratio of the change in y-values to the change in x-values for this function? a) 1: 13 b) 2: 5 c) 5: 2 d) 13: 1

Vikram is studying the square pyramid below. on st to find the surface area of the pyramid, in square inches, vikram wrote (33.2) (34 ikram wrote (33.2)(34.2)+43(34.2)(284) what error did vikram make? o he used the same expression for the area of all four lateral faces. he used the wrong expression to represent the area of the base of the pyramid. o he used the wrong value as the height when he found the area of the lateral faces. he used an expression for surface area that only finds the total area of three faces.
