The difference between the sample mean and the population mean is called the:""
1 answer:
Answer: Option 'D' is correct.
Step-by-step explanation:
If there is difference between the sample mean and the population mean, then it is known as "Sampling error".
As we know that standard error of the mean is given by
and the sampling error refers to the difference in the value of sample mean and the value of population mean.
Hence, Option 'D' is correct.

Answer:
Step-by-step explanation:
We first have to write the equation for the sequence, then finding the first five terms will be easy. Follow the formatting:
and we are given enough info to fill in:
and
and
or in linear format:
where n is the position of the number in the sequence. We already know the first term is -35.
The second term:
so
and
The third term:
and
so
and we could go on like this forever, but the nice thing about this is when we know the difference all we have to do is add it to each number to get to the next number.
That means that the fourth term will be -27 + 4 which is -23.
The fifth term then will be -23 + 4 which is -19. You can check yourself by filling in a 5 for n in the equation and solving:
and
so
