Answer Z = -1/4
Step-by-step explanation:
-1/3+2z= -5/6
Add 1/3 to both sides
-1/3+2z+1/3 = -5/6+1/3
Simplify
2z=-1/2
Divide both sides by 2
2z/2 = -1/2/2
Simplify
z = -1/4
Answer: it already is.
Step-by-step explanation: The more pieces are cut, the smaller they get so the bigger the denominator, the bigger the piece
Using the z-distribution, as we are working with a proportion, it is found that the 99% confidence interval for the proportion of all U. S. Adults who would include the 9/11 attacks on their list of 10 historic events is (0.7458, 0.7942). It means that we are 99% sure that the true proportion for all U.S. adults is between these two bounds.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
In this problem, the parameters are:

The lower limit of this interval is:

The upper limit of this interval is:

The 99% confidence interval for the proportion of all U. S. Adults who would include the 9/11 attacks on their list of 10 historic events is (0.7458, 0.7942). It means that we are 99% sure that the true proportion for all U.S. adults is between these two bounds.
