According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (bac) is 0.340.34. suppose a random sample of 114114 traffic fatalities in a certain region results in 5151 that involved a positive bac. does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive bac than the country at the alpha equals 0.1α=0.1 level of significance? because np 0 left parenthesis 1 minus p 0 right parenthesisnp01−p0equals=nothing ▼ greater than> equals= not equals≠ less than< 10, the sample size is ▼ less than greater than 5% of the population size, and the sample ▼ is given to not be random, is given to be random, can be reasonably assumed to be random, cannot be reasonably assumed to be random, the requirements for testing the hypothesis ▼ are not are satisfied.

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) ).
