For practical purposes, sampling with replacement and sampling without replacement are comparable as long as only a small fraction of the population is sampled,
In sampling with replacement, the two sample values are independent. In sampling without replacement, the two sample values aren't independent.

Answer:
Variable cost per unit= $2.27 per machine hour
Explanation:
Giving the following information:
January 3,041 $4,032
February 3,456 $4,608
March 4,147 $6,912
April 5,184 $9,101
May 3,686 $5,760
June 5,322 $9,216
To calculate the unitary variable cost, we need to use the following formula:
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (9,216 - 4,032) / (5,322 - 3,041)
Variable cost per unit= $2.27 per machine hour
