Research Scenario: Does distraction or amount of details affect the ability of people to make good decisions?
In this fictitious scenario, researchers used a mixed design. Thirty participants were split into two groups – No Distraction or Distraction (n=15 per group). All participants were given TWO scenarios based on amount of details (4 or 12), and were asked to make an objective decision at the end of each scenario. Objective decision was the dependent variable and was quantified numerically using an interval scale of measurement.
Assume the data is parametric. Select and conduct the most appropriate statistical test to determine whether distraction or amount of details affect people’s ability to make good decisions.
Let level of significance = 0.05.

To test the distraction affect people’s ability to make good decisions, Calculated F= 35.2851, P=0.0000 which is greater level of significance 0.05 level. We conclude that distraction affect people’s ability to make good decisions.
To test the amount of details affect people’s ability to make good decisions, Calculated F= 64.1963, P=0.0000 which is greater level of significance 0.05 level. We conclude that amount of details affect people’s ability to make good decisions.
To test the interaction between distraction and amount of details , Calculated F= 1324.9978, P=0.0000 which is greater level of significance 0.05 level. We conclude that interaction is significant.
Answer:
What percentage of pick-up truck drivers want their next vehicle purchase to be another pick-up truck?
Should the speed limit be decreased on the highway connecting two large cities?
How many pedestrians would use a walkway built over a busy road?
Step-by-step explanation:
We use samples when using an entire population is not feasible.
It is not reasonable to ask every pick-up truck driver what they want their next purchase to be; there are too many owners of pick-up trucks. This means we should use a sample.
Many people drive a highway that connects two large cities. It is not reasonable to survey every person that drives it, so we should use a sample.
On a busy road, we may have many pedestrians; this means we should use a sample instead of the entire population.
Answer:
B. 4/5
Step-by-step explanation:
Answer:
(1) commutative property of the addition.
(2) distributive property of the multiplication and associative property of the addition.
(3) addition property of the equality.
(4) multiplication property of the equality.
Step-by-step explanation:
First we start with:
4x + 1 + x + 3 = -11
Here we use the commutative property of the sum, which says that:
A + B = B + A
So we can reorder the terms in a sum, and we can rewrite our equation as:
4*x + x + 3 + 1 = -11
Here we also used the associative property of the sum, that says that:
A + B + C = (A + B) + C = A + ( B + C)
wich means that we can perform the sum in any order we want, then we can add the 3 and the 1
4*x + x + 4 = -11
Now we use the distributive property of the multiplication, which says that:
(A + B)*C = A*C + B*C
Then we can rewrite our equation as:
(4 + 1)*x + 4 = -11
Now we solve the sum in the parentheses to get:
5*x + 4 = -11
Now we can use the addition property of the equality, we can add (-4) in both sides to get:
5*x + 4 - 4 = -11 - 4
5*x = -15
Now we can use the multiplication property of the equality, and multiply both sides by (1/5) to get:
5*x*(1/5) = -15*(1/5)
x = -5
