Scanned with CamScanner10. You wish to estimate, with 95% confidence, the proportion of senior high students in your school whoread the first book of Harry Potter. Your estimate must be accurate within 2% of the populationproportion. With no preliminary estimate available, what is the minimum sample size that you need?C. at least 2506D. at least 2605A. at least 2301B. at least 2401

Since there is no prior information about the population proportion, it is considered as p=0.5. It…

Find an article of your choice which uses proportions, and copy and paste the address of that article in this step. Identify at least one sample proportion within the article (you can list more than one if you like), and state what that sample proportion measures. For example, if you're told that the sample proportion of people in Renton who are taller than 5'11" is 80.7%, and you're also told that the sample size is 57, then you would state the proportion as 46/57 in your response for this part of the assignment. You will probably have to interpret what is being said in the article in order to be able to state specifically what the sample proportion represents. Also, you might not have � or �, you might only have the percentage or a decimal equivalent. Often, the size of the sample is stated somewhere in the article, and it's important to find that value. So, if � is given, please include it in this part of the assignment. If stated in the article, identify whether the sample is a…

A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 95% confident that his estimate is in error by no more than five percentage points? Complete parts (a) through (c) below. a) Assume that nothing is known about the percentage of computers with new operating systems. n=0.250.25 (Round up to the nearest integer.) b) Assume that a recent survey suggests that about 99% of computers use a new operating system. n=nothing (Round up to the nearest integer.) c) Does the additional survey information from part (b) have much of an effect on the sample size that is required? A. No, using the additional survey information from part (b) does not change the sample size. B. No, using the additional survey information from part (b) only slightly increases the sample…
You are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. How many randomly selected air passengers must you survey? Assume that you want to be 95% confident that the sample percentage is within 4.5 percentage points of the true population percentage. Complete parts (a) and (b) below. a.

Assume that a prior survey suggests that about 37% of air passengers prefer an aisle seat. n = (Round up to the nearest integer.)
I ask 32 residents of Klamath Falls if they own a house. If I would like to make sure that my sample is approximately normal, how many more residents (if any) must I ask, given the fact that (somehow) I know that 62 percent of all residents own a house.
A programmer plans to develop a new software system. In planning for the operating system that he will use, hee needs to estimate the percentage of computers that use a new operating system.
