Answer:
a) 35
b) 47
c) there is no mode because no observation is repeated
Step-by-step explanation:
a)
sum of observation = (34 + 23 + 10 + 45 + 44 + 47 + 35 + 37 + 41 + 30 + 28 + 32 + 45 + 39) = 490
total number of observation = 14 = n
mean = ( 490/14 ) = 35
b)
47 is the highest marks score
c) there is no mode because no observation is repeated
