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.
10
Therefore, the greatest common factor of 30 and 50 is 10.
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Probability that they were left handed P(L)= 40%
Probability that they were Democrats P(D)= 47%
So, P(L∩D) = 135 = 0.13
Now, to check whether they are independent or not.
We will find P(L) × P(D) is given by
Since P(L) . P(D) ≠ P(L∩D)
So, they are not independent.
Hence, Option 'c' is correct.
Answer:
The area is 45 units squared
Step-by-step explanation:
If the rectangle's width is 3 units, and the length is 5 times then:
5 x 3 = 15
So the length is 15 units
The area is length times width
15 x 3 = 45
The area is 45 units squared
Hello!
1 quart=4 cups
4(4)=16
1/4(4)=4/4
16+4/4=16 4/4
Our final answer is 16 4/4 cups.
I hope this helps!
