Determine the point estimate of the population proportion th

Determine the point estimate of the population proportion, the margin of error for the fllowing confidence interval and the number of individuals in the sample with the specified characteristic of x, Lower bound = 0.313 Upper bound = 0.857, n= 1000 point estimate of population proportion ?

Solution

Lower bound = 0.313 Upper bound = 0.857

Margin of Error = (0.857 - 0.313)/2 = 0.272

Point of estimate = Middle of the 2 observation = 0.313 + 0.272 = 0.585
