Question 16 Researchers want to study whether.or.not a fear of flying is related to a fear of heights. They surveyed a large group of people and asked them whether or not they had a fear of flying and whether or not they had a fear of heights. The data are shown in the contingency table below. What is the relative risk of being afraid of heights for those who are afraid of flying? Round your answer to two decimal places. location has nothing to do with team preference, the probability that the data gathered was the result of chance is calculated to be 0.03. What is the correct interpretation of this calculation? Select the correct answer below. Afraid of heights 76 Not afraid of heights 33 Total 109 Afraid of flying 82 370 452 Not afraid of flying 158 404 561 Total More people from rural areas want the defending champions to win the game. Exactly 216 out of every 374 urban residents want the defending champions to win the game. The results are statistically significant at the 0.05 level of significance in showing that the proportion of people in rural areas who want the defending champions to win the game is different than the proportion of people in urban areas. The data is not statistically significant at the 0.05 level of significance in showing that the proportion of people in rural areas who want the defending champions to win the game is different than the proportion of people in urban areas. Provide your answer below: Question 18 A student wants to know his average homework grade for the first half of his math class. There were 7 homeworks in the first half of the class, and his grades out of 100 are given by 100,90,95,89,92,85,95. What is the population mean of his homework grades? Round your answer to the nearest tenth. Question 21 Find the mode of the following amounts (in thousands of dollars) in savings accounts of randomly selected people aged 25-30. Provide your answer below: 8,6,8,7,2,2,2,4,4,4,4,7 Provide your answer below: Question 20 A poll was conducted during the final game of the basketball season to determine whether fans wanted to see the defending champions win the game or the challenging team win the game. From the poll, 216 of the 374 residents sampled from urban areas want the defending champions to win the game. In more rural areas, 304 of the 466 residents polled want the defending champions to win the game. Assuming Question 22 A deck of cards contains red cards numbered 1,2,3,4,5,6, blue cards numbered 1,2,3,4,5 and green cards numbered 1,2,3,4,5,6,7,8. If a single card is picked at random, what is the probability that the card is red?
