In a regression study of factors affecting learning time for a certain task (measured in minutes), gender of learner was included as a predictor variable (x2) that was coded x2 = 1 if male and 0 if female. it was found that î²ë 2 = 22.3 and s(î²ë 2) = 3.8.

an observer questioned whether the coding scheme for gender is fair because it results in a positive coefficient, leading to longer learning times for males than females?

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
