Final answer:
To find missing monetary amounts, we should compare the totals given, identifying the greater and lesser values; for sampling distribution, normal or t-distribution could be used; and in probabilities, joint and conditional probabilities should be applied.
Step-by-step explanation:
To determine the missing amount from the given situations, we should list other known quantities and identify the 'given' information as well as what is to be 'found'.
Let's take the totals provided and try to establish comparisons which could be part of a question such as identifying greater and lesser amounts:
- $56.75
- $43.25
- $65.00
- $25.50
- $18.75
- $59.00
- $21.50
- $44.50
- $12.50
- $43.00
- $89.50
- $99.35
- $235.75
- $300.50
- $678.25
For the statistics problem (question 128), we would use the sampling distribution of the sample mean if we assume the central limit theorem applies; hence, the answer would be a normal distribution if the sample size is large enough, or a t-distribution for smaller sample sizes.
For questions dealing with probability (questions 129 and 130), the joint probability and conditional probability are pertinent: the probability of both a drought and water rationing is 0.02 (20% of 10%), and the probability of a drought given that water rationing has happened is 0.4 (the 20% probability of drought out of the 5% probability of water rationing).
