First find the cumulative frequency of the data

#

Interpolation, use CF and see where does 50 lie within

#

Then take the limits of the boundaries for where the 50th value lies

#

Limits of mass and number of students

#

50-(lower limit)/(range of class) = x-lower limit of mass/range of mass class

Your Mean mass is also wrong

#

Huh? Elaborate please

west bramble May 5, 2024, 4:31 PM

#

I don't think it is?

#

You got the total frequency wrong

#

Ohhhhhhhhh, I have corrected it

#

Thank you

#

The mean I got is 53.36

#

And the standard deviation is 2.9552

#

I have found the cumulative frequency too
