Answer:
The correct option is D. No, because a random sample from all customers of the shopping mall was not selected
Step-by-step explanation:
In statistics, Bias can be described as a term which depicts error if a sample is not taken evenly or it depicts errors taken from an unjust sampling.
In statistics, sampling bias means the errors which occur if one part of the population is favoured more then the rest of the populations. In this kind of bias, the individuals for experimentation are not chosen randomly.
As the customer satisfaction survey was distributed in only one of the gates hence, it does not give a generalized result and the result is biased.
Do you have a picture would probably make more sense if you added one
Answer:
Step-by-step explanation:
equation of a circle
we know the center is (-7, 3)
the radius is 2
we replace (h,k) with the center coordinates
and input the radius
simplify to this:
7xp-6xp+2+8

Answer:
What was the regular price of the T-shirt?
What question is being asked in this word problem?
- what is the regular cost of the t-shirt purchased by Jill.
What is the regular price of the skirt?
How much money does Jill have left?
- without considering sales tax, Jill has $90 - $31 = $59 left.
- If I use the sales tax from where I live, the sales tax = $1.86, so the money that Jill will have left = $59 - $1.86 = $57.14
How much does the T-shirt normally cost?
What is the amount Jill pays in sales tax?
- since you do not include the sales tax % in the question, I will simply use the sales tax from where I live = $31 x 6% = $1.86
Step-by-step explanation:
skirt $21
t-shirt = p - $8
before sales tax, total cost was $31
$21 + p - $8 = $31
p = $18
