Five classmates want to know how many of the 2520 students in their school prefer pop music. They each randomly survey 60 students. The table shows the results. Favorite Type of Music Country Pop Rock Rap Shannon 14 20 15 11 Trey 12 23 14 11 Robert 13 18 17 12 Callie 15 20 14 11 Lani 15 19 13 13 Use the results from each classmate to make an inference about the number of students in the school who prefer pop music. Based on Shannon's results, the number is students. Based on Trey's results, the number is students. Based on Robert's results, the number is students. Based on Callie's results, the number is students. Based on Lani's results, the number is students. Question 2 Describe the variation of the five inferences. Which one would you use to describe the number of students at the school who prefer pop music? Explain. The greatest is students. The least is students. The median of the data is . The mode of the data is . So, use the inference of students to describe the number of students at the school who prefer pop music.

If the speed of an electromagnetic wave is 100,000 cm/s and its wavelength is 100 cm, what is its frequency? a) 100,000 cycles per second (hz) b) 1 × 10-3 cycles per second (hz) c) 10,000,000 cycles per second (hz) d) 1,000 cycles per second (hz)

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
