Answer:
The upper endpoint of the 99% confidence interval for population proportion is 0.13.
Step-by-step explanation:
The confidence interval for population proportion is:
<u>Given:</u>
<em>n</em> = 1000
= 0.102
*Use the standard normal table for the critical value.
Compute the 99% confidence interval for population proportion as follows:
Thus, the upper limit of the 99% confidence interval for population proportion is 0.13.
Answer:
the rewritten equation
the equation in one variable:
the solution for the system:
Step-by-step explanation:
system of equations is:
If we multiply the second equation by 4, we can rewrite it like this:
this last equation has the form
so now we sum this equation to the unchanged equation:
we get the equation with one variable .
If you need to solve the whole system, we clear for y in the last equation:
and using the first original equation we subtitute to find
