Add all the expenses together ( $2.00 + $1.50 + 0.50 +1,000 = 1004) divide 1004 by $14 to get 72
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:
$120 billion
Explanation:
Economy operating at $300 billion above its natural level of output.
Marginal propensity to consume, MPC = 3/5 = 0.6
For closing this expansionary gap, the government have to decrease its spending by the amount calculated as follows:
Spending multiplier:
= 1/ (1 - MPC)
= 1/ (1 - 0.6)
= 1/ 0.4
= 2.5
Hence, the government spending reduces by
= Expansionary gap ÷ Spending multiplier
= $300 ÷ 2.5
= $120 billion
