The percentage of University of Illinois students that have taken either Economics 102 or 103 is 85 %. Suppose random samples of 225 students are taken. Find the value where 1% of the sample proportions are greater than that value.
I need help understanding the last part of this problem and how I can use it in the formula. Thanks
The formula I was thinking of was p(1-p)/n but I dont think that will work. The 1% part of the problem is giving me trouble. Could you explain what you mean on the last part of what you wrote about Z being the critical value at
Can you tell me the right formula to use because I think I had the wrong one in mind?Thanks
