Ex 13.1, 2 Consider the following distribution of daily wages of 50 workers of a factory. Find the mean daily wages of the workers of the factory by using an appropriate method. Mean(𝑥 ̅) = a + h × (∑▒𝒇𝒊𝒖𝒊)/(∑▒𝒇𝒊) Where a = Assumed Mean h = Class interval Also, ∑▒𝒇𝒊 = 50 ∑▒𝒇𝒊𝒖𝒊 = −12 Putting values in formula Mean(𝒙 ̅) = a + h × (∑▒𝒇𝒊𝒖𝒊)/(∑▒𝒇𝒊) 𝑥 ̅ = 550 + 20 × (−12)/50 𝑥 ̅ = 550 – 4.8 𝒙 ̅ = 545.2 Therefore, mean average wage is Rs 545.2
