Answer:
The 99.9% confidence interval for the population proportion is (0.548, 0.896).
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:
99.9% 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 99.9% confidence interval for the population proportion is (0.548, 0.896).
Imma start that lesson in about two years so sorry I can’t answer this question I
Answer:
x= and x=
Step-by-step explanation:
- transfer the -1 to the other side so that the equation reads as
- factor! think about what numbers add -4 but also multiply to be 1
- you may then realize that there are no numbers with those characteristics
- since that is the case, we have to use the quadratic formula, which is:
and
- the equation is shown as
- using the numbers that correspond with those lettered values, plug it in the quadratic formulas
It’s 5 i’m pretty sure have a good day
