Answer:

mean of the funds by 'step deviation = 987.5

Step-by-step explanation:

Class           Frequency          Mean  u= (Mean - 1250)/500    Frequency * u

0- 500                     35           250      -2                                     -70

500-1000                 28          750     -1                                      -28

1000-1500                32          1250    0                                      0

1500-2000                15          1750     1                                       15

2000-2500               10          2250    2                                      20

         Total               120                                                              -63

Mean = 1250  + (-63/120) * 500

= 1250  - 262.5

= 987.5

mean of the funds by 'step deviation = 987.5
