Answer:
Mean = 41.2
Range = 18
Step-by-step explanation:
(a)Mean = Sum of all observations/ total number of observations
Sum of observations = 38+42+50+37+38+47+50+43+35+32 = 412
Total number of observations = 10
∴ Mean = 412/10 = 41.2
(b) Range = Maximum value of the given data - Minimum value of the given data
Maximum value of the given data = 50
Minimum value of the given data = 32
∴ Range = 50-32 = 18
