Answer:
$40,000 (U)
Explanation:
Given that,
Flexible-budget variance for materials = $2,000
Price variance for material = $38,000
Sales-volume variance = $13,000
Efficiency variance for direct manufacturing labor = $9,000 (F)
Flexible-budget variance for materials = Price variance for material + Efficiency variance for materials
2,000 (U) = 38,000 (F) + Efficiency variance for materials
Efficiency variance for materials = 2,000 + 38,000
= $40,000 (U)
Answer: Simple random
Explanation: In statistics, a simple random sample is a subset of individuals chosen from a larger set. Each individual is chosen randomly and entirely by chance, such that each individual has the same probability .In this technique, each member of the population has an equal chance of being selected as subject. The entire process of sampling is done in a single step with each subject selected independently of the other members of the population. Simple random sampling is a method used to cull a smaller sample size from a larger population and use it to research and make generalizations about the larger group . Simple random sampling is the most basic and common type of sampling method used in quantitative social science research and in scientific research generally.
The probability that he will call A is 1 out of 2 because A and B have the same percent of Hazard. The probability that he will call C is 0/3 because it is more hazardous than the rest.
