There is a relationship between confidence interval and standard deviation:

Where

is the mean,

is standard deviation, and n is number of data points.
Every confidence interval has associated z value. This can be found online.
We need to find the standard deviation first:

When we do all the calculations we find that:

Now we can find confidence intervals:

We can see that as confidence interval increases so does the error margin. Z values accociated with each confidence intreval also get bigger as confidence interval increases.

Answer:
Option B.
Step-by-step explanation:
The non-uniform probability is when the event is not same in the occurring of event.
Option A is uniform because there will be equal chance of getting head or tail.
Option B is non-uniform because sum can be any number if we get(3,4) it will be 7 and if we have (2,3) then it will be 5.
Option C is uniform because we have equal number of red and green balls so, selecting a ball from both will be same.
Option D is uniform because chance of 1,2,,3,4,5 or 6 will be equal chance from rolling a die that is 1/6 in all cases.
Therefore, Option B is correct
Answer:
X=4
Step-by-step explanation:
28+8=36
36/9=4
9*4=36
36-8=28
x=4
Answer:
when rounding anything that is or is greater than 5 you round up 1.
4,->7<-08.06
so rounding up 1, 4 would turn into 5.
