Answer:
30
Step-by-step explanation:
Given :
Mean, m = 30 metric tons
Standard deviation (s) = 1.5 metric ton
Sample size, n = 4
Since the impact force in the test model is normally distributed, the shape of the sampling distribution will also be approximately normal with a mean equal to the mean of the test model.
Hence, the sample mean impact force will be equal to the population mean.
Therefore, sample mean = 30 ; population mean = 30
