First put them in order: 12, 12.2, 12.3, 12.6, 12.8, 12.8, 13.5, 13.9, 14, 14.2. The minimum (the lowest) is 12. The median (the middle number) is 12.8. The third quartlile is approximately 13.9. The first quartile is 12.25. He lied about the first quartile :)
Answer:
Parameter
Step-by-step explanation:
We are given the following in the question:
The average age of men who had walked on the moon was 39 years, 11 months, 15 days.
Population and sample:
- Population is the collection of all observation for variable of interest or individual of interest.
- Sample is a subset for population.
Parameter and statistic:
- Any variable or value describing a population is known as parameter.
- Any value describing a sample is known as statistic.
Population of interest:
men who had walked on the moon
Value:
average age of men who had walked on the moon
Thus, the give value describes a population and hence, it is a parameter.
The answer is C) Multiply 4 by the difference of 10 and 3, then add 5
