A new radar system is being developed to successfully detect a majority of packages dropped by airplane. In a series of random trials, the radar detected the packages being dropped 39 times out of 56. (a) Calculate the point estimate, standard error, margin of error, and the appropriate bound for an 80% one-sided confidence interval/bound for the proportion of all packages being dropped that are detected. (Round your answers to 4 decimal places, if needed.) Point estimate = Standard error = Margin of error = The corresponding interval is ( 1). (b) Based on this one-sided confidence interval, does a population proportion value of 0.7 seem appropriate? O No, since the interval is completely above 0.7. O Yes, since the interval is completely above 0.7. O No, since the interval contains 0.7. O Yes, since the interval contains 0.7.

Question
A new radar system is being developed to successfully detect a majority of packages dropped by airplane. In a series of random trials, the radar detected the
packages being dropped 39 times out of 56.
(a) Calculate the point estimate, standard error, margin of error, and the appropriate bound for an 80% one-sided confidence interval/bound for the
proportion of all packages being dropped that are detected. (Round your answers to 4 decimal places, if needed.)
Point estimate =
Standard error =
Margin of error =
The corresponding interval is
1).
(b) Based on this one-sided confidence interval, does a population proportion value of 0.7 seem appropriate?
O No, since the interval is completely above 0.7.
Yes, since the interval is completely above 0.7.
O No, since the interval contains 0.7.
Yes, since the interval contains 0.7.
