(A) Find the standard deviation from the following data using short cut method:Ageunder1020304050607080No. of15305375100110115125personsdyingHint: 1. Convert first row into class intervals. These class intervals will represent the classintervals for “Age" now not “Age under".2. Convert second row into frequencies.3. Use the result that “standard deviation is independent of change of origin but not independentof change of scale" i.e. if d¿ = , then ơx = hơa.X¡-Ah
