Question

A research group conducted an extensive survey of 2915 wage and salaried workers on issues ranging from relationships with their bosses to household chores. The data were gathered through hour-long telephone interviews with a nationally representative sample. In response to the question, "What does success mean to you?" 1625 responded, "Personal satisfaction from doing a good job." Let p be the population proportion of all wage and salaried workers who would respond the same way to the stated question. Find a 90% confidence interval for p. (Round your answers to three decimal places.)

Lower Limit:

Upper Limit:

Thanks!

Answer 1

Given that, n = 2915 and x =1625

Using TI-84 calculator we get, 90% confidence interval for population proportion of p is, ( 0.542, 0.573)

Where, Lower Limit = 0.542 and

Upper Limit = 0.573
