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).
0≤h(t)≤144, which means that the height of the object can be between 0 and 144 feet, including those limits.
Then,
3^y = 7, is equivalent to y = log_3(7)
We need to find which graph goes like log_3(x). For x =3, log_3(3) = 1, for x = 9, lo_3(9)=2, so .....
The first one!
