A simple random sample "is a subset of a statistical population in which each member of the subset has an equal probability of being chosen"
In other words that means in order to apply a random sampling we need to ensure that we have the same probability of inclusion for every possible element of the population of interest.
And for this case a collection of any numerical information is not referred as random sampling since we don't know if these scores are representative of the population of interest.
And we don't know if this information is obtained using any sampling frame or sampling methodology.

Answer:
The sum of the first six terms is
Step-by-step explanation:
Given series is 32-8+2-0.5+...
We may write
Let
Common ratio
Therefore the common ratio is
Therefore given sequence is of the form of Geometric sequence
The nth term of the geometric sequence is
First to find the 5th and 6th term
That is substitute n=5 and n=6 ,a=32 and in above equation we get
Therefore
Therefore
Therefore the sum of the first six terms is
Therefore the sum of the first six terms is
Answer: x=2
Step-by-step explanation:
