Σf = 5 + f1 + 10 + f2 + 7 + 8. Σf = 30 + f 1 + f 2. F +f2=229−(12+30+ +25+) = −150. Σfx = 2060 + 30f 1 + 70f 2. Mean = 2× 1 + 5× 2 + 4× 3 + 2× 4 + 1× 5 2 + 5 + 4 + 2 + 1. 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 Then f1+f2 t o al frequency−sum of the given frequency.

Use the formula (# +#)/2=median and solve. Σf = 5 + f1 + 10 + f2 + 7 + 8. After finding missing frequency determine standard deviation and coefficient of vari.

Of number/items) so, take the sum of all objects and divide it by no. We have a median, lower limit. Only mathdude500 will answer no one will give answer show your whole working for 4th quest. Find the missing frequencies and the median for the following distribution if the mean is 1.46. Then f1+f2 t o al frequency−sum of the given frequency.
