Answer: B. Population X will require a larger sample size
Step-by-step explanation:
- If a random variable say p has skewed distribution (whether right or left ) in a population then a bigger sample size is needed to make sure that the sampling distribution follows normal distribution.
Given : Two population distributions labeled X and Y.
Distribution X → highly skewed
Distribution Y → slightly skewed.
Since Distribution X more skewed so , we will need a larger sample size of population X as compared to Y.
Hence, the correct answer is B. Population X will require a larger sample size
Answer:
11 -√20
Step-by-step explanation:
If you want ...
√20 + x = 11
You can find x by subtracting √20 from both sides of the equation:
x = 11 -√20
The number you're looking for is 11 -√20.
Answer:
Step-by-step explanation:
You can do this in a conventional mathematics way by showing each digit as an increasing power of 8, starting with zero
E.g 325 octal
(3 * 8 2 ) + (2 * 8 1 ) + (5 * 8 0 ) = (3 * 64) + (2 * 8) + (5 * 1)
i.e 192 + 16 + 5 = 197 decimal
Note: any number raise to power of 0 in indices is equal to 1
Do you mean what two numbers can be divided into 450?
The conclusion is valid
it is a systematic random sample
and the second one is a line graph (I think)
