Deermine the point estimate of the population proporton the margin of error for following oonfidence interal, and the number of individuals in the sample with the specifed characteristcs for the sample size provided Lower bound 0.563, upper bound 0.877, n 1200 The estimate of the population proportion (Round the nearest thousandth as needed The margin of emor is (Round to nearest thousandth as needed.) The number of individuals in the sample with the speofid characteristic is (Round the nearest integer needed Enter your answer ineach of the answer boxes

Explanation / Answer

Solution:-

1)

Confidence interval = (0.583, 0.877)

a) The point estimate of population proportion is 0.73.

p = (Lower limit + Upper limit)/2

p = 0.73

b) Margin of error = + 0.147

Confidence interval = p + M.E

M.E = 0.73 - 0.583

M.E = + 0.147

c) The number of individual in the sample with specified characteristics is 876.

p = x/n

x = p × n

x = 1200 × 0.73

x = 876
