In sampling what is A universe?

Universe is the total population from which the sample is drawn. For example, if you are sampling 500 houses from a city that has 10,000 houses, the universe here is the 10,000 houses.


In a sample of 500 students 50 percent attend college within 50km of their homes The probability that the population proportion will be between 0.45 and 0.55 is?

According to the theory behind a sampling distribution of a proportion, when you take a sample proportion with mean p from a sample of n people, the actual population proportion will follow a normal distribution of mean p with a standard deviation of √(p*(1-p)/n). Using the information given, our sample had a mean, p, of .5 and a sample size, n, of 500. Therefore, the mean of the population is .5 and the standard deviation is √(.5*(1-.5)/500)=.022361. Next, in order to find our probability, we need to calculate the z-scores of our 2 bounds using the formula z=(x-mean)/standard deviation. For .45 this gives (.45-.5)/.022361=-2.236 and for .55 we get (.55-.5)/.022361=2.236. In order to convert this into a probability, we will need to look these values up in a z-table and find the area between them. Doing that we find that the area must be .974653. This tells us that the probability that the population proportion is between 0.45 and 0.55 is 97.4653%.

How big is 500 meters squared?

I have some trouble understanding your question. I will answer the following questions: a) What is the area of a square, 500 m on a side? Ans: 500 x 500 = 250,000 m2. b) If I had a square with an area of 500 m2, what is the size of each side? sqrt(500) = 22.3 m
