A 2x2 experiment looks at how obesity and hunger affect the amount of food people eat. The results are shown below. n=10 participants per condition. Additional info if needed: N=40, G=120, ∑2=640 ∑
x
2
=
640

please conduct a twoway ANOVA and draw conclusions about the main effects and interaction of obesity and hunger on food intake.

Obesity (Factor B)
B1 (Obese) B2 (normal weight)
Hunger A1 (not hungry)
M=4 SS=50

M=1 SS=30
Factor A A2 (hungry) M=5 SS=60 M=2 SS=40

is this a dating site too?

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.

im guessing (23,14). hope this : )

can i know which language is this?
