Apilot sample of 75 items was taken, and the number of items with the attribute of interest was found to be 30. how many more items must be sampled to construct a 99% confidence interval estimate for p with a 0.025 margin of error?

2474

Step-by-step explanation:

Given : A pilot sample of 75 items was taken, and the number of items with the attribute of interest was found to be 30.

Then, prior estimate for proportion of attribute of interest:

Significance level :

Critical value :

Margin of error :

The formula use to find the sample size :_

Now, simplify , we get

Now, the number of items more to sample =

yes

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
