Step-by-step explanation:
Answer: k = 59°
Steps:
180 - 77 = 103
103 + 18 + k = 180
121 + k = 180
k = 180 - 121
k = 59
Check:
103 + 18 + k = 180
103 + 18 + 59 = 180
180 = 180 ✅

Answer:
The 80% confidence interval for the population proportion of disks which are defective is (0.059, 0.079).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
Suppose a sample of 1067 floppy disks is drawn. Of these disks, 74 were defective.
This means that 
80% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 80% confidence interval for the population proportion of disks which are defective is (0.059, 0.079).
