Answer:
1000 represents the sample

What does 1000 represent?
First, we should know that 1000 adults were picked or selected from a larger number of adults.
This implies that:
The larger number of adults is the population and the 1000 selected adults represents the sample.
The 2 ratios are almost equivalent, but not quite. In order to tell if they are equivalent, there are a number of ways but the 2 most common are 1, finding the decimal equivalent of the fraction, and 2, finding the scale factor.
1: Take 16, divide by 14. You should get something around 1.142. Take 64, divide by 60. You should get something around 1.066666.... Not equivalent.
2: Find the scale factor between the 2. To find scale factor, divide the larger numerator and larger denominator by the smaller numerator and smaller numerator. 64/16, 60/14. Not equal.
Given:
15 students
2 students must be chosen.
No repetition, no order
This is a combinations problem. We use this formula: n! / (n-r)!(r!)
n = 15 ; r = 2
15! / (15-2)!(r!) ⇒ 15! / 13! * 2! = 105
Hello,
The correct answer is D) 2
Median: To find the Median, place the numbers you are given in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. Put them in order: {10, 11, 13, 15, 16, 23, 26} The middle number is 15, so the median is 15. (If there are two middle numbers, you average them.)
The median number of trips taken to the food store in 1 week is 2.
4 - 2 = 2
Hope this helps!!!! :)
