Answer:
The correct answer is option D.
Explanation:
Technological change refers to an improvement in the efficiency of a product such that the output level increases without an increase in input.
Here, the rearranging of layout and training of workers is technological change as they are likely to increase production without an increase in inputs.
Damages caused by a hurricane will reduce the output level, so it will not be classified as a technological change.
Answer:
This is a stratified random sample because a separate random sample is selected from each class
Explanation:
Stratified random sampling is an appropriate method when the population consists of mixed characteristics and you would like to ensure that every characteristic is proportionally represented in the sample. In this example, the population is the students from Central High School and the mixed characteristics are the different classes such as Freshman students, Sophomore students, Juniors and Seniors.
After the population is divided into subgroups based on characteristics, from the overall proportion of the population, you calculate how many people should be sampled in each subgroup. Random or systematic sampling can then be used to select a sample from each subgroup.

Answer:
$400,000
Explanation:
total variable manufacturing overhead = sum of total machine hours required during the year x variable manufacturing overhead rate per machine hour
= (35,000 hours + 20,000 hours + 15,000 hours + 30,000 hours) x $4 per machine hour = 100,000 machine hours x $4 per machine hour = $400,000
total fixed manufacturing overhead = $50,000 per quarter x 4 quarters = $200,000
