j: The arthmatic mean of two observations is 127.5 and their geometric mean is 60.
Find (i) their harmonic mean and (i) the two observations:
6: (a) Show that in finding the A.M. of a set of readings on a thermometer, it does not matter whether we measure the temperature in Centigrade (C) or Fahrenheit (F) degrees.
7:
(a). Evaluate an appropriate measure of dispersion for the following data Less than.
Income In Dollars: 50, 50-70, 70-90, 90-110, 170-130, 130-150, Above 150.
No. of persons, 54, 100, 140, 300, 230, 125, 51
(b) Comment on the following:
If the coefficient of quartile deviation (Q.D) is 0.6 and QD= 15. then Q1 - 10 and Q3 = 40.
