Answer:
-1
Step-by-step explanation:
Since 34 is an even number, we can factor a 2 out of the exponent of your problem, like this:
i34=(i2)17.
But, i2=-1, so your problem becomes:
-117.
This means, multiply -1 by itself 17 times, to get -1
(Remember, -1 raised to an odd power is always -1, so -117=-1.)
The final answer is:
i34=-1
Answer:
The 99% confidence interval for the proportion of all American adults who blame Barack Obama a great deal or a moderate amount for U.S. economic problems is (0.4894, 0.5706)..
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 .
For this problem, we have that:
99% 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 99% confidence interval for the proportion of all American adults who blame Barack Obama a great deal or a moderate amount for U.S. economic problems is (0.4894, 0.5706)..
