Answer: 9% parameter, 3% statistic
Step-by-step explanation: Parameter and statistic are are statistical terms used to describe a group or observation.
However, the distinction between a parameter and a statistic is in the measured observation.
Parameter is used to describe an entire population while statistic is used to describe a sample.
Where a population refers to the entire number of people or inhabitant of a particular country while a sample refers to a subset of observation drawn randomly from a population which serves a representative of the entire population.
In the question above, 9% is used to make a description of the whole American population who are at least 75 years of age. While,
3% is used to describe a subset of the American population (sample) who are 75 years or older.
We know that
volume of a cone=(1/3)*pi*r²*h
<span>If the height of a cone is cut in half
so
h=h/2
and
new volume of a cone=</span>(1/3)*pi*r²*(h/2)----> (1/2)*[(1/3)*pi*r²*h)
the answer is
<span>the volume of the cone is multiplied by 1/2</span>
(100/15)x493=$3286.67 (rounded to 2 decimal places)
The one above is wrong.
This is the correct way:
(100/85)×493=580
Correct answer is $580
For 70 people i would say ab 445
