The bis which is likely for the given question by the researcher is response bias.
Given that,
A researcher calls 1,800 randomly chosen residential telephone numbers, and then asks to speak with an adult member of the household.
The researcher asks, “How many 3D movies have you watched in a movie theater in the past 12 months?”.
Response bias happens when the people who needs to respond does this in an inaccurate way or wrongly.
Here almost no people will be correctly remembering the exact number of movies they watched in a year.
Also, they may be volatile to social desirability and may say less or more number of movies.
So there happens a response bias.
Hence the correct bias is response bias.

Step-by-step explanation:
5 men to 270 women
5 (men) : 270 (women)
make the ratio as small as you can by dividing the same number on both sides.
5 : 270. both sides can be divided by 5
1 : 54
It means for every 1 man working, there are 54 women working
The ratio of men to women in the factory is calculated by dividing the number of men by the number of women and simplifying the result. In this case, the ratio is 1:54, meaning for every man, there are 54 women.
The question asks to find the ratio of men to women in a factory where there are 5 men and 270 women working. To calculate the ratio of men to women, we simply divide the number of men by the number of women.
The calculation would be as follows:
However, ratios are typically expressed in simplest form. Since both 5 and 270 are divisible by 5, we divide each by 5:
This means that for every man in the factory, there are 54 women.

Answer: the probability that there are three or fewer calls in one hour is 0.011
Step-by-step explanation:
The formula for poisson distribution is expressed as
P(x = r) = (e^- µ × µ^r)/r!
Where
µ represents the mean of the theoretical distribution.
r represents the number of successes of the event.
From the information given,
µ = 10
For the probability that there are three or fewer calls in one hour, it is expressed as
P(x ≤ 3) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)
Therefore,
P(x = 0) = (e^- 10 × 10^0)/0! = 0.000045
P(x = 1) = (e^- 10 × 10^1)/1! = 0.00045
P(x = 2) = (e^- 10 × 10^2)/2! = 0.0023
P(x = 3) = (e^- 10 × 10^3)/3! = 0.0077
Therefore,
P(x ≤ 3) = 0.000045 + 0.00045 + 0.0023 + 0.0077 = 0.011
Answer: a=24
Step-by-step explanation:
Lets find the line's formula (equation of the line).
As known the general formula of any straight line (linear function) is
y=kx+b
Lets find the coefficient k= (Yb-Ya)/(Xb-Xa)=(9-7)/(-4-3)=-2/7
(Xb;Yb)- are the coordinates of point B
(Xa;Ya) are the coordinates of point A
Now lets find the coefficient b. For this purpose we gonna use the coordinates of any point A or B.
We will use A
7=-2/7*3+b
7=-6/7+b
b=7 6/7
So the line' s equation is y= -2/7*x+7 6/7
Now we gonna find the value of a usingcoordinates of point C.
Yc=1, Xc=a
1=-2/7*a+7 6/7
2/7*a= 7 6/7-1
2/7*a=6 6/7
(2/7)*a=48/7
a=48/7: (2/7)
a=24
Answer:
a=24
Step-by-step explanation:
What is the average number of siblings for this group? Enter your answer as a decimal, rounded to the nearest tenth,
_______
The average number of siblings for the group is 1.3.
We must compute the total number of siblings and divide it by the total number of children in the group to determine the average number of siblings for the group.
There are a total of: siblings in the bunch.
3 + 8 + 9 = 20 (1 sibling times 3 children) + (2 siblings times 4 children) + (3 siblings times 3 children)
The total number of kids in the group is: 5 + 3 + 4 + 3 = 15
As a result, the group as a whole has an average of:
20/15 = 1.33 (rounded to the nearest tenth) (rounded to the nearest tenth)
So, the group as a whole has 1.3 siblings on average.
