Transcribed Image Text:From the sample statistics, find the value of p1 - P2, the point estimate of the difference of proportions. Unless otherwise indicated, round to the
nearest thousandth when necessary.
The U.S. Department of Labor and Statistics wanted to compare the results of an unemployment program for the past two months in the U.S. Suppose the
proportion of the unemployed two months ago is p2 and the proportion of the unemployed one month ago is p1. A study found a 99% confidence interval
for p2 - P1 to be (-0.0012, 0.003). Give an interpretation of this confidence interval.
Seleccione una:
O A. The probability that the proportion of the unemployed two months ago is between 0.12% less and 0.3% more than the unemployed one month ago is
99%.
O B. We are 99% confident that the proportion of the unemployed two months ago is between 0.12% less and 0.3% more than the proportion of the
unemployed one month ago.
O C. If samples were repeatedly drawn from the same populations under the same circumstances, the true population difference (p2 - P1) would be
between -0.0012 and 0.003 99% of the time.
O D. The probability that the proportion of the unemployed one month ago is between 0.12% less and 0.3% more than the unemployed two months ago is
99%.
O E. We are 99% confident that the proportion of the unemployed one month ago is between 0.12% less and 0.3% more than the proportion of the
unemployed two months ago.
