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 Mathematics, 02.02.2019 20:10
Asystem of linear equations with fewer equations than unknowns is sometimes called an underdetermined system. can such a system have a unique solution? explain. choose the correct answer below. a. yes, it can have a unique solution. because there are more equations than variables, there are no free variables. if the system is consistent and there are no free variables, the solution set contains a unique solution. if the system is inconsistent, there is no solution. b. no, it cannot have a unique solution. because there are more variables than equations, there must be at least one free variable. if there is a free variable, the solution set contains a unique solution. c. no, it cannot have a unique solution. because there are more variables than equations, there must be at least one free variable. if the linear system is consistent and there is at least one free variable, the solution set contains infinitely many solutions. if the linear system is inconsistent, there is no solution. d. yes, it can have a unique solution. because there are more variables than equations, there must be at least one free variable. if the linear system is consistent and there is at least one free variable, the solution set contains either a unique solution or infinitely many solutions. if the linear system is inconsistent, there is no solution.
God bless you.
