Answer:
The 90% confidence interval is 0.575 to 0.625.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval , 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:
90% confidence interval
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 90% confidence interval is 0.575 to 0.625.

Answer:
<h3> -5n = 1 ⇒
n = -¹/₅</h3><h3> n+15 = (-10) ⇒ n = 25</h3><h3> n/5 = -1/5 ⇒ n = -1</h3><h3> n-13= -12 ⇒ n = 1</h3>
Step-by-step explanation:
-5n = 1
÷(-5) ÷(-5)
n = -¹/₅
n + 15 = (-10)
-15 -15
n = -25
n/5 = -1/5
×5 ×5
n = -1
n - 13 = -12
+13 +13
n = 1
The answe is 12. formula is 2/3x=8
