Calvin's school is 2.3 miles directly south of his house. After school, he
takes a bus 1.8 miles directly west to the sports complex.
Part A
What is the length of a straight line between Calvin's house and the sports
complex? Round to the nearest tenth.
Part B
Calvin takes piano lessons at a community music school located 3.7 miles
directly north of the sports complex. What is the length of a straight line
between Calvin's house and the music school? Round to the nearest tenth.

Atown has a population of 17000 and grows at 2.5% every year. to the nearest year, how long will it be until the population will reach 19600?

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) ).
