Pls tell the answer /
malfutka [58]

Step-by-step explanation:

I assume AB is supposed to be a straight line. yes ?

in that case please remember that all angles on top of a line (and then again below a line) must sum up to 180 degrees (this is what it takes to flip a "stick" on that line from left to right).

so, COD covers already 90 degrees of these 180.

that means AOD + BOC = 180 - 90 = 90 degrees.

now we know that the 2 angles are in the ratio of 1:5.

that means that BOC is 5 times as large as AOD.

and we can be more direct :

since the 2 angles are in the ratio 1:5 we are actually splitting the remaining 90 degrees into 6 parts (5+1).

and BOC gets then 5 of these 6 parts, and AOD gets the remaining 1 part.

so,

90/6 = 15

therefore, one of these parts is 15 degrees.

so, we know AOD = 15 degrees.

BOC = 5×15 = 75 degrees

or simply 90 - 15 = 75 degrees

Does distraction and/or amount of details affect the ability of people to make good decisions? In this fictitious scenario, rese
makkiz [27]

Answer:

Result:

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.

Excel used for calculations:

[Find the 4 attachments]

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.
