Explanation / Answer

Mean = Total/ number of observation

= 783.4/8

= 97.925

Mean = 97.92

b) To calculate median Ordering the data from least to greatest, we get: 62.2,75.2,91.5,94.7,103.2,108.6,119.6,128.4

Middle most values 94.7, 103.2

Take average of these two numbers 94.7+103.2/2

= 197.9/2

Median = 98.95

c) Mode does not exist because all values appeared just once.
