Using confidence interval concepts, it is found that the incorrect statement is given by:
B. The population proportion is 0.80.
In a sample of n people with a proportion of , and a confidence level of
, we the <u>confidence interval for the proportion</u> is:
In which z is the z-score that has a p-value of .
80 developed immunity out of 100, thus, the sample proportion is:
<em>Option A </em>is correct.
The standard error is:
Considering
Thus,<em> statement E</em> is correct.
<u>90% confidence level,</u> thus the critical value is the value of z that has a p-value of , so
, which means that <em>statement D</em> is correct.
The margin of error is:
Thus, <em>statement C</em> is correct, which leaves B as the false statement, as we have the sample proportion, and we can only estimate, not guarantee the population proportion.

Answer:
r=1
Step-by-step explanation:
<u>Ratio of Values </u>
A ratio compares two values by diving them. If the ratio is greater than one, then the value in the numerator is greater than the value in the denominator. The opposite relation gives ratios lower than 1. A ratio of 1 means both values are the same
We have a set of tiles numbered 1 to 30:
1,2,3,4,5,6...,29,30
Note that each odd-numbered tile is followed by an even-numbered tile. It means we have 15 odd tiles and 15 even tiles. The ratio is
r=1
