Suppose that the owner of a fast food restaurant recently purchased a new soft drink machine, designed to dispense 16 oz for a small beverage. the actual amount dispensed is normally distributed and should have a mean of 16 oz, but the manager suspects that the machine may be underfilling the cups. he selects a random sample of 7 small soft drinks, as filled by the machine. the volumes dispensed into each cup, in ounces, are listed below. 15.7,15.8,15.6,16.1,16.0,15.7,15.5

Plz ( true - false) all triangles have interior angles whose measure sum to 90.

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
