The original mean of the data is 1.8
The mean of the data of the piece of data is increased by ten is 11.8
the mean of the data of the piece of data is doubled is 3.6
The formula for calculating the mean of numbers is expressed as:
Mean = Sum/N
N is the total number present
GIven the set of data 2.4, 1.6, 3.2, 0.3, 1.5
Sum = 2.4 + 1.6 + 3.2 + 0.3 + 1.5
Sum = 9
N = 5
Mean = 9/5 = 1.8
The original mean of the data is 1.8
b) If the piece of data is increased by ten, hence the new sum of data will be:
New sum = 9 + 10(5) = 59
New mean = 59/5 = 11.8
Hence the mean of the data of the piece of data is increased by ten is 11.8
c) If the piece of data is doubled, hence the new sum of data will be:
New sum = 2(9) = 18
New mean =18/5 = 3.6
Hence the mean of the data of the piece of data is doubled is 3.6
