Answer:
Estimated mean diameter of the 53 oranges = 50mm
Step-by-step explanation:
To find the estimated mean diameter one would find the mean of the selected sample of the total population
Since the 8 samples are selected at random from a population of 53 oranges
Estimated mean diameter = (45+46+42+53+60+49+54+51)/8
= 400/8
= 50mm
Estimated mean diameter of the 53 oranges = 50mm
