Students in a school were asked to collect old bottles as part of a recycling drive. some of the data recorded at the drive is shown in the histogram below: a histogram is shown with title recycle drive collection. on the horizontal axis the title is number of bottles. the title on the vertical axis is students. the range on the horizontal axis is 0 to 3, 4 to 7, and 8 to 11. the values on the vertical axis are from 0 to 10 at intervals of 1. the bar for the first range is till 3, the bar for the second range is till 6, the bar for the third range is till 1. which information is not provided in the histogram? the number of students who collected exactly 2 bottles the total number of students who collected bottles the number of students who collected 4 or more bottles the total number of students who collected 8 or more bottles

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
