Since it involves all values in the data-set, the measure most affected by outliers is given by:
A. the mean
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
The median is the 50th percentile, while the mode is the value that appears the most often in the data-set, that is, they do not involve outliers, only the mean does, hence option A is correct.

Answer:
y=-3
Step-by-step explanation:
2y+3y=4−6−13
2y+3y=4+−6+−13
(2y+3y)=(4+−6+−13)
5y=−15
5y=−15
y= −3
Answer:
z= 2.38
P = 0.008656
Step-by-step explanation:
Here n= 500 and p~= 464/500= 0.928 and q`= 1- 0.928 = 0.072
We formulate our null and alternate hypothesis as
H0 = 0.9 ; H0 > 0.9
The degree of confidence = 90%
z₀.₀₅ = 1.645 for α= 0.05
We use the test statistic
z= x- np/√npq
z= 466-500 *0.9/ √500 * 0.9(1-0.9)
z= 466- 450/ √45
z= 16/6.7082
z= 2.38
As the calculated value of z= 2.38 is greater than α =1.645 so we reject H0.
If H0 is true the P value is calculated as
P = 1- Ф( 2.38)
P = 1-0.991344=0.008656
It’s the first one (2,2)(3,5)(4,0)
