Answer:
B. <em>There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>
Step-by-step explanation:
A. <em>One has 90% confidence that the sample proportion is equal to the population proportion. </em>
Confidence interval gives an interval estimate, not an equality
B. <em>There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>
<em>Ture. </em>
<em>C.</em><em> One has 90% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion. </em>
Also true but <em>One has 90% confidence is not good interpretation. </em>
<em>D</em><em>. 90% of sample proportions will fall between the lower bound and the upper bound.</em>
<em>Lower bound and upper bound is given to estimate population proportion. </em>
Answer:
Step-by-step explanation:
12,800 written as 1.28 x 104 in scientific notation
Answer:
x≥2
Step-by-step explanation:
First, write out the equation as you have it:
Then, add 
to both sides:
Next, subtract 
from both sides:
Finally, divide both sides by 
:
or
Therefore: the answer to this inequality/equation is: x≥2
