Answer:
(0.4062, 0.5098)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval
, we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of
For this problem, we have that:
356 dies were examined by an inspection probe and 163 of these passed the probe. This means that and
Assuming a stable process, calculate a 95% (two-sided) confidence interval for the proportion of all dies that pass the probe.
So = 0.05, z is the value of Z that has a pvalue of
.
The lower limit of this interval is:
The upper limit of this interval is:
The correct answer is
(0.4062, 0.5098)
