Find the missing frequencies f1 and f2 , if median of given frequency
Find the missing frequencies and the median for the following distribution if the mean is 1.46. Σf = 5 + f1 + 10 + f2 + 7 + 8. So, we have, x+y=30 we can find the other equation by equating the mean value by sum of (fm/m) then solve the 2 equations for x and y 15+f 1+21+f 2+17=10015+f 1+21+f 2+17⇒f 1+f 2=47.(i)25015×10+30×f 1+50×21+70×f 2+90×17=53150+30f 1+1050+70f 2+1530=131250.(ii)on. Concept notes & videos 366. Mean = 2 + 10 + 12 + 8 + 5 14 = 3714 = 2.64. Calculate the median age, if policies are only given to persons having age 18 years onwards but less than 60 years. To make these videos i use following products. So, missing frequency is 15. ← prev question next question →.
Find the mode of the data. So, we have, x+y=30 we can find the other equation by equating the mean value by sum of (fm/m) then solve the 2 equations for x and y 3 f 1 + 7f 2 = 252. If it is, you can take the median and the one of the two numbers you know. Σf = 5 + f1 + 10 + f2 + 7 + 8. ← prev question next question →. Aboat goes downstream from one part of the river to another part of river in 16 hours it covers the same distance upstream in 20 hours if the speed of stream is 2 km per hour find. Substitute this value of x in equation (1) to get the value of y. Ation show your whole working for this question and i am warning: Mean = 2× 1 + 5× 2 + 4× 3 + 2× 4 + 1× 5 (how many numbers) and rather than count how many numbers there are, we can add up the frequencies: Mean = (sum of all numbers/items)/(no.
