Step-by-step explanation:

Refrigerator           50 dB

Electric toothbrush  60 dB

Sewing Machine      60 dB

Washing machine    70 dB

Electric Shaver         70 dB

Dishwasher              70 db

Alarm clock             80 dB

ELectrical drill        90 dB

Car Horn                  110 dB

Ambulance Siren    120 dB

Mode = 70 db  ( repeating 3 times)

Mean = Sum/10 = 780/10 = 78 dB
