Will give ! 3 1. a spinner has six sections of equal shape and size. each section is either black or white. the table shows the result of an experiment when the spinner was spun 76 times: result of spin black white number of spins 19 57 based on the data, which of the following best describes the experimental probability of the arrow landing on a black or white section of the spinner? (5 points) select one: a. the spinner is 3 times more likely to land on white. b. the spinner is 3 times more likely to land on black. c. the information cannot be concluded from the data. d. the spinner is equally likely to land on black or white. 2. two groups performed an experiment separately by tossing a coin in the air. group p performed 50 trials and group q performed 100 trials. each group recorded the results in the table below: group heads tails p 35. 15 q 53 47 what conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails? select one: a. the experimental probability and the theoretical probability for group p is the same. b. the experimental probability and the theoretical probability for group q is the same. c. the experimental probability is closer to the theoretical probability for group q than group p. d. the experimental probability is closer to the theoretical probability for group p than group q. 3. the teacher of a seventh-grade class flipped a coin 100 times. the students recorded the results in the table shown below: side of coin landed on heads tails number of flips 56 44 which of the following best describes the experimental probability of getting tails? select one: a. the experimental probability is same as the theoretical probability. b. the experimental probability is 6% lower than the theoretical probability. c. the experimental probability is 6% higher than the theoretical probability. d. the experimental probability cannot be concluded from the data in the table.

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.

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
