A sales representative for a new soft drink is trying to convince a chain of food stores to order a much larger quantity. The
salesperson uses the graph below in the sales pitch. What is deceptive about the graph?
Sales of Mango Mango
Sales (in 10,000's)
Mar.
O
Jan. Feb.
a. The vertical scale needs more intervals between values.
b. Sales for February and March appear to be greater than they actually ar
C. Sales for January appear to be much smaller than they actually are.

Icould really use some with this question.

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) ).

Explain how you would construct a perpendicular bisector of wx using a compass and a straightedge. (31 points guys)
