Using the z-distribution, it is found that the 90% confidence interval is given by: (0.6350, 0.6984).
<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, we have a 90% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 1.645.
The sample size and the estimate are given by:
Hence, the bounds of the interval are given by:
The 90% confidence interval is given by: (0.6350, 0.6984).

Answer: its -0
Step-by-step explanation:
Answer:
49.2 - 12.3 = 36.9
Step-by-step explanation:
Difference in Math terms means Subtract
For this case we have the following definition:
tens place: number of two digits whose absolute value is greater than zero.
Then, we have the following rounding rule:
If the previous number is greater than or equal to five, the next number increases by one unit.
We then have the following numbers rounded to 30 when rounded to the nearest ten:
26: twenty-six
27: twenty-seven
Answer:
two different numbers that round to 30 when rounded to the nearest ten are:
26: twenty-six
27: twenty-seven
