Step-by-step explanation:
I've graphed this on desmos for a visual
If the number of samples is increased, this actually leads
to a reduction in error of the distribution. This is because of the
relationship between variation and sample size which has the formula of:
σx = σ / sqrt (n)
So from the formula we can actually see that the variation
and sample size is inversely proportional.
Which means that increasing the sample size results in a
reduction of variation.
Answer:
It will have less variation
Answer:
P odd number, then 20) = 1 /14
Step-by-step explanation:
P( odd number) = number of odd numbers/ total
number of odd numbers = 3
total = 7
P( odd number) = 3/7
We keep the tile so that there are only 6 tiles left
P (20) = number of 20/ total
= 1/6
We multiply the probabilities together
P odd number, then 20) = 3/7 * 1/6 = 3/42 = 1 /14
