A company makes three chocolate candies: cherry, almond, and raisin. Matrix A gives the number of units of each ingredient in each type of candy in one batch. Matrix B gives the cost of each ingredient (dollars per unit) from suppliers X and Y. What is the cost of 100 batches from supplier X? Matrix A is 3 by 3 with columns labeled from left to right as follows: sugar, chocolate, milk and rows from top to bottom labeled as follows: cherry, almond, raisin. The matrix contains the following elements from left to right where the row is listed first and the elements are listed second: row 1, 4, 6, 1; row 2, 5, 3, 1; row 3, 3, 3, 1. Matrix B is 3 by 2 with columns labeled from left to right as follows: X, Y and rows from top to bottom labeled as follows: sugar, chocolate, milk. The matrix contains the following elements from left to right where the row is listed first and the elements are listed second: row 1, 3, 2; row 2, 3, 4; row 3, 2, 2.

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
