Statistics help!!!!?

Determine the point estimate of the population proportion, the margin of error for the following confidence interval, and the number of individuals in the sample with the specified characteristics, x, for the sample size provided.

Lower Bound=0.482, upper bound=0.918, n=1000

1 Answer

  • Point estimate of the population proportion = Sample proportion = [0.482 + 0.918] / 2

    = 0.7

    Margin of error = [0.918 – 0.482] / 2

    = 0.218

    Sample proportion = x/n

    0.7 = x/1000

    x = 700

    Therefore, the number of individuals in the sample with the specified characteristic x = 700
