As part of a drug trial, a survey was done to gather information about the participants' experiences with side effects. Here are the results . 662 people participated in the drug trial in all 365 of the participants had anxiety 67 of the participants had fatigue , but had neither anxiety nor dizziness 131 of the participants had dizziness, but had neither anxiety nor fatigue 143 of the participants had anxiety, but had neither fatigue nor dizziness of the participants had both anxiety and fatigue, but didn't have dizziness 109 of the participants had both anxiety and dizziness, but didn't have fatigue 616 of the participants had at least one of these three side effects (anxiety, fatigue, dizziness)

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
