Problem 2: Bagging and Tagging (and re-Bagging) (30 points) One of your scientific advisors points out that surely, surely any sufficiently advanced species capable of sending

drones to another planet would obfuscate their serial numbers, maybe even randomize them, to try to keep their

targets from doing exactly what you did in Problem 1 to try to estimate their numbers. Obviously you can't just

count all the drones directly - there'd be no way to be sure you caught them all, and there might be more out there,

Which statement accurately explains whether a reflection over the x-axis and a 180° rotation would map figure acb onto itself?

Rectangle pqrs has length a and width 4b. the x-axis bisects ps and qr what are the coordinates of the vertices

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
