Question

Collect data(in decibels) pf ten different things in turms of loudness arrenge the data in ascending order and find maen,median and mode for the same

Answer 1

Normal conversation 65dB
Telephone dial tone 80dB
City Traffic 85dB
Train whistle 90dB
Train Running 95dB
Hand Drill 98dB
Motorcycle 100dB
Rock Music Concert 115dB
Pneumatic machine 125dB
Jet engine 140dB

Mean =  $\frac{65+80+85+90+95+98+100+115+125+140}{10}$

         = $\frac{993}{10} = 99.3 dB$

Median = Average of Two Middle most values of the data = $\frac{95+98}{2} = \frac{193}{2} = 96.5dB$ 

There is no MODE for the data as none of the data is repeating.
