Answer:
It is true that the sampling distribution of the proportions is approximately a normal distribution.
Explanation:
Solution
Given that:
N = 50
P= 0.8
Thus
p ^ =√p(1-p)/n
p ^=√0.8 (1-0.8)/50
p ^= 0.0566
Therefore,we conclude that the sampling distribution of the proportions is approximately a normal distribution.

Answer:
If analyzed by volume capacity, more trips are needed to fill the space, thus the required trips are 288
Explanation:
a) By volume.
The shrinkage factor is:

The volume at loose is:

If the Herrywampus has a capacity of 30 cubic yard:

b) By weight
The swell factor in terms of percent swell is equal to:


The weight of backfill is:

The Herrywampus has a capacity of 40 ton:

If analyzed by volume capacity, more trips are needed to fill the space, thus the required trips are 288
