We want to find out if gender has any effect on how fast people detect emotions. We set up a study where we record the number of

seconds it takes for a person to correctly identify the emotion portrayed in a picture. We recruit an equal number of men and women to participate in our pseudo-experiment and then compare the times between men and women. What type of analysis should we use?

Answer:

Independent samples t-test

Step-by-step explanation:

The Independent Samples t-test also known as the two sample t-test is a parametric test that compares the means of two unrelated groups in order to test whether there is a significant statistical evidence are from populations having different mean values.

Hence, to find out if gender has any effect on how fast people detect emotions;

- We set up a study where we record the number of seconds it takes for a person to correctly identify the emotion portrayed in a picture.

- We recruit an equal number of men and women to participate in our pseudo-experiment and then compare the times between men and women.

This type of analysis is the Independent samples t-test.

Helena wrote the equation using point-slope form for the line that passes through the points (5, 1) and (3, 5). Analyze the step
viva [34]

Answer:

In step 2, she didn’t use an x and y from the same coordinate pair

Step-by-step explanation:

see the attached figure to better understand the problem

we have the points (5, 1) and (3, 5)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute

m=\frac{5-1}{3-5}

m=\frac{4}{-2}

m=-2

step 2

The equation of the line in point slope form is

y-y1=m(x-x1)

take the point (3,5)

m=-2

substitute

y-5=-2(x-3)

y-5=-2x+6

y=-2x+6+5

step 3

y=-2x+11

therefore

In step 2, she didn’t use an x and y from the same coordinate pair
