What sample size is necessary for a study
What sample size is ncessary for a study to determine the average cost of a child delivered at a local hopsital within the past 3 months? (I have determined a sample size of 1,300. I came up with this number because there are 10,416 births a year in Louisville, KY where the basis of this problem is. 10,416 / 12 months = 868. 868 x 3 months = 2,604 so I am taking half of that and rounding to 1,300.
The remainder of the question is: The mean sample is estimated to be $10,000 with a population standard deviation of $1,500 and the research objectives are a 95% confidence interval and the error range is $500.© SolutionLibrary Inc. solutionlibary.com July 14, 2020, 11:04 pm 9836dcf9d7 https://solutionlibrary.com/statistics/data-collection/what-sample-size-is-necessary-for-a-study-f59v
