Question 2 In a survey of 50 students, 15 students said they liked football. The number of students who like football is 15, and the ________ (frequency/relative frequency) is __________ (fill in the fraction or decimal). Now, Relative frequency = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑠𝑡𝑢𝑑𝑒𝑛𝑡𝑠 𝑤ℎ𝑜 𝑙𝑖𝑘𝑒 𝑓𝑜𝑜𝑡𝑏𝑎𝑙𝑙)/(𝑇𝑜𝑡𝑎𝑙 𝑠𝑡𝑢𝑑𝑒𝑛𝑡𝑠) = 15/50 = 𝟑/𝟏𝟎 Thus, our fill in the blank is The number of students who like football is 15, and the relative frequency is 𝟑/𝟏𝟎
