A researcher predicts that popularity of college football is greater at her university than the average of football popularity in all US schools. To find out, she samples 144 students at her university and finds a mean popularity score of 70 (s = 8). The average football popularity for all students at all US schools is 80. If the mean difference gets larger and sample standard deviation stays the same, what happens to effect size?

answer: 1, 3 and 5 are correct

step-by-step explanation:

what? that isnt a question

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
