The answer would be: <span>99.0%
</span>
The disease is rare with a prevalence of <span>one out of every thousand people have it. That means, the chance of Roberto has the disease without any test would be 1/1000 or 0.1%
The test sensitivity is 99%, which mean 99% of people with positive test result would have the disease. The chance is should not be influenced by the disease prevalence. </span>
Place the values in ascending order first:
4, 10, 10, 11, 12, 12, 12, 12, 13, 13, 15, 15, 17, 18, 19, 20
There are 16 values
IQR is 3/4th term - 1/4th term
The 12th value is 15 while the 4th value is 11
Therefore IQR = 15-11 which is 4
I would say the outlier is 4.
Justification: Figure out the mean with the value of 4 then discount it to see whether the mean is affected by the outlier.
Answer:

Step-by-step explanation:
<u>Step 1: Determine the equation</u>
So we know that our equation does not have a y-intercept which means that it doesn't intersect ANYWHERE on the y-axis. Therefore, this means that our equation will be a straight vertical line that doesn't move side to side and just goes straight up and down. We also know that our point is (3, 6) which means that our x-value will be 3 and this is where the equation will be located.
There are several ways to display our answer where x = 3 is the most common way which basically means give me all of the y-values for the same x value of 3. Another way of saying it is x - 3 = 0 which either way when adding 3 to both sides gives you x = 3 which is what I usually go with.
Answer: 
The greatest common factor of 14x-24 is 2. So it would be 7x - 12
Answer: He will have $1721.28. after 4 years.
Step-by-step explanation:
The formula we use to find the compounded amount A is :
, where P= principal value, r = rate of interest , t= time.
As per given , we have
P=$1500 , r=3.5%=0.035 , t= 4 years
Money he will have after 4 years = 

Hence, he will have $1721.28. after 4 years.
