Answer:
Step-by-step explanation:
If repeated sample sizes of large sizes are taken at random, and proportion P is calculated for samples the sample mean will have a normal distribution irrespective of the original distribution.
In other words, the sample proportion will follow a normal distribution with mean = p-hat and std deviation =
This is a direct corrollary of central limit theorem for sample means.
Hence we have irrespective of sample size, sample proportion will have expected value same as p-hat.
So whether sample size is 500 or 100 the p hat will have the same distribution.
Answer:
5/8 is greater than 3/5
Step-by-step explanation:
you could also convert the fractions so they have the same denominator and then compare which numerator is larger.
Answer:
A'(5, -3)
Step-by-step explanation:
Reflection over the x-axis changes the sign of the y-coordinate:
(x, y) ⇒ (x, -y)
A(5, 3) ⇒ A'(5, -3)
Answer:
k = 20
Step-by-step explanation:
310-(30x7) = 5k
310-210=5k
100=5k
/5 /5
20=k
