Use the sample data and confidence level to construct the confidence interval estimate of the population p....n=5200, x=4821, 99% confidence

  • Statistics (incomplete) -

    What is the Standard Deviation (SD)? Do you mean "x=4821" or ∑x = 4821 to calculate the mean?

    99% = mean ± 2.575 SEm

    SEm = SD/√n
