A. Simple random sample is to be selected from a thousand chicken at the poultry farm to
estimate the amount of chicken feeds consumed at the poultry farm in a specific period. Its
known that the range for the chicken feeds is 80 . Given a total estimate of 200500 grams of
chicken feeds with a bound on the error of estimation of 900 grams, calculate the estimated
variance of the average amount of chicken feeds. B. The academic performance of boys, at SQU
in general, is less than for the girls. In a pool of 1000 male students, 40% blamed the out-campus
housing problem for this unsatisfactory performance, 35% blamed themselves, and the rest
blamed the education system. Under a significant level of 5%, does the evidence suggest that the
true proportions who blame housing problems and education system, respectively, are different
and why?
