I have a proportion that is .5972 and a mean that is .5984.

I have a standard error of .0681 and a standard deviation of .0688.

What can explain the relationship between proportion and mean and the relationship between standard error and standard deviation that makes these numbers so similar but different>

More info: Found proportion and standard error by dividing number of houses sold by houses with fireplaces and then using the standard error formula with a sample size of 50. Found mean and standard deviation by drawing 1000 random samples with a sample size of 50.

I have started thinking of nursing as an art. I mean by this that nurses have to be very good at the art of caring and building a trustworthy relationship with their patients. I also didn't realize how much nurses remember their patients. I always thought that nursing was a tough job and I knew that you always had to do what was best for your patient but I never really thought about the doctor considering the nurse's opinion or...

I have the following statistics problem. Katrina wants to estimate the proportion of adult Americans who read at least 10 books last year. To do so, she obtains a simple random sample of 100 adult Americans and constructs a 95% confidence interval. Mathew also wants to estimate the proportion of adult Americans who read at least 10 books last year. He obtains a simple random sample of 400 adult Americans and constructs a 99% confidence level. Assuming both Katrina and...

I compared Coke and Pepsi cans. For Coke I have n= 36 sample mean = 12.19 oz. and s = .11. For the Pepsi cans I have n=36 sample mean = 12.29 oz. and s =.09. I wish to determine if the two brands provide the same volume per can. Is it reasonable to pool the sample variances? Why or why not? How many degrees of freedom for this problem Compute spool Compute the margin of error for the confidence interval Test the claim...

Sample statistics, such as the sample mean or the sample proportion, can be used to estimate...

Sample statistics, such as the sample mean or the sample proportion, can be used to estimate a population parameter (such as the population mean or the population proportion). For example, you can estimate the true mean weight of all newborn babies in the entire world by collecting a sample and using that sample to generate a 95% confidence interval. Because the sample is typically a relatively small portion of the entire population, errors will have to be considered. Using a...
