(ENEM-2013) A survey was carried out in 200 hotels in a city, in which the values, in reais, of the daily rates for a standard double room and the number of hotels for each daily rate were noted. The daily rates were: A = R$200.00; B = R$300.00; C = R$400.00 and D = R$600.00. In the graph, the areas represent the number of hotels surveyed, in percentage, for each daily rate. The median daily rate, in reais, for a standard double room in this city is a) 300.00. b) 345.00. c) 350.00. d) 375.00. e) 400.00. 02. (ENEM-2018) The Internal Accident Prevention Committee (CIPA) of a company, noting the high costs of frequent work-related accidents, conducted, at the request of the board of directors, a survey of the number of accidents suffered by employees.

(ENEM-2018) Students of the statistics discipline, in a university course, take four assessments per semester with weights of 20%, 10%, 30% and 40%, respectively. At the end of the semester, they need to obtain an average in the four assessments of at least 60 points to pass. A student of this discipline obtained the following points in the first three assessments: 46, 60 and 50, respectively. The minimum points that this student needs to obtain in the fourth assessment to pass is a) 29.8. b) 71.0. c) 74.5. d) 75.5. e) 84.0. 05. (ENEM-2016) The graph shows the average daily oil production in Brazil, in millions of barrels, from 2004 to 2010. Estimates made at that time indicated that the average daily oil production in Brazil, in 2012, would be 10% higher than the average of the last three years presented in the graph. If the estimates had been confirmed, the estimated average daily oil production in Brazil, in millions of barrels, in 2012, would have been equal to a) 1.940. b) 2.134. c) 2.167. d) 2.420. e) 6.402.
