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).
L'Shonda purchased a container of juice. 80 calories are from carbohydrates.
<u>Solution:</u>
Given that, LShonda purchased a container of juice that contains 200 calories.
The label says that 40% of the calories are from carbohydrates.
We have to find how many calories are from carbohydrates?
Now, according to the given information,
<em>Number of calories from carbohydrates = 40% of the total calories of the juice
</em>
Then, calories from carbohydrates = 40% of 200 calories
40% can be written in fraction as 

Hence, 80 calories are from carbohydrates.
