The statement that is true about the given sample is that;
B. The sample includes all customers who made complaints to the company within the last year, and therefore is representative of the population. ,
<h3>Sample Statistics Interpretation</h3>
We are given;
Sample size; n = 420
Sample proportion; p^ = 65%
Now, from the sample size and proportion, we can say that;
Exactly 65% of the surveyed customers were not satisfied with the cell phone service. Now, this only represents those surveyed and not the entire population. Thus it is not exactly 65% of all customers that are not satisfied with the cell phone service.
Option B is correct because the 420 customers surveyed is a sample from the population of all their customers within the last year.

Answer:
0 (Zero)
Step-by-step explanation:
Mary has jogged each day for the past nine days. The data of her jogging is:
6, 7, 5, 0, 6, 12, 8, 6, 9
Now, we need to figure out the outlier.
We need to define what is an outlier:
"Outliers" are those values that "lie outside" the other values. Here in the given data set, it lies at an abnormal distance from other values in a random sample. We can see that all the values are ranging in a particular interval except 0.
0 in the given data set is lying outside of the other values. Therefore, 0, is the outlier in the given data set.
Answer:
cout << setprecision(3) << fixed << x;
Step-by-step explanation:
If rad=3pi/2 then the angle is 3pi/2*180/pi
To find the answer, combine like terms:
3p + p = 4p
4 + 12 = 16
3q has no like terms so it stays the same.
Now put them all together:
4p + 3q + 16 = Option A).
