Answer:
a) 120
b) 30
c) Because we can estimate the mean with the mid range
Explanation:
a)
The mid range can be calculated as
Mid range=(minimum value+maximum value)/2
Mid range=(60+180)/2
Mid range=240/2
Mid range=120
b)
The standard deviation can be computing by dividing the range by 4.
Range=maximum-minimum
Range=180-60
Range=120
Standard deviation=120/4
Standard deviation=30
c)
Assumption of normality is important because mean and standard deviation can be estimated from mid range using normality.
