Sagot :
Let's analyze each part of the question step-by-step:
1. Data Analysis:
From the table provided, we have the following percentages for each blood type:
- Type AB: 0.12 (or 12%)
- Type B: 0.10 (or 10%)
- Type O: 0.42 (or 42%)
- There is no percentage given for Type A directly.
2. Part (b): Identifying the Most Common Blood Type:
- From the given data, the percentages for each blood type are:
- AB: 12%
- B: 10%
- O: 42%
- A: Not provided explicitly, but we can infer it is the remaining percentage of the population.
- Among the listed values, 42% is the highest percentage.
- Therefore, the most common blood type is Type O.
3. Part (c): Identifying the Least Common Blood Type:
- From the provided data:
- AB: 12%
- B: 10%
- O: 42%
- A: As inferred, it is the remaining percentage which is 0% in this context.
- Among the given types, the least percentage is 0% for Type A.
- Therefore, the least common blood type is Type A.
4. Part (d): Conjecture on the Percentage of the Population with Type O Blood:
- From the data, Type O blood type comprises 42% of the sample population.
- Using this sample to project or conjecture the population percentage is an example of inferential statistics because we are making an inference from the sample data to the broader population.
- Hence, the correct percentage is 42%, and it is an example of inferential statistics.
Therefore, the correct answer for part (d) is:
- A. 42%; inferential
Summary:
- Part (b): The most common blood type is Type O.
- Part (c): The least common blood type is Type A.
- Part (d): 42%; inferential.

- Part (d): 42%; inferential.
