Jane obtains three mutant strains (a, b, and c) of true-breeding, white-flowered sweet peas. purple is the wild-type flower color. when a and b or b and c are crossed, the f1 are all purple-flowered. when either of these purple f1 are selfed, about 44% of the progeny are white and the rest are purple. when strains a and c are crossed, the f1 are all white. when these white plants are selfed, only 0.010% of the progeny are purple. explain these data in terms of complementation and intragenic recombination.

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
