Consider the following regression line: T e s t s c o r e ^ = 698.9 − 2.28 S T R . You are told that the t-statistic on the slope coefficient is 4.38. What is the standard error of the slope coefficient?

0.52

Step-by-step explanation:

Given the regression line :

Test score^ = 698.9 - 2.28STR

T statistic on slope Coefficient = 4.38

The standard error on slope Coefficient :

2.28 / 4.38

= 0.5205479

= 0.52

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
