Researchers want to determine the effects of gender and socioeconomic status (i. e. high, medium, and low) on student achievement. What is the appropriate test to use? 1) ONe-way anova
2) t-test for independent samples
3) t-test for dependent samples
4) two-way anova

Two way ANOVA.

Step-by-step explanation:

The two way analysis of Variance statistical analysis technique is used to analyae and determine the variation in sample means. The two way ANOVA is considered when the independent variable is more Than one. Usually two, in the scenario described, the independent variables in the scenario are ; Socioeconomic Status and Gender.

Also.in Analysis of Variance, the groups or factor level of each independent variable must the atleast 3 or more, this factor level serves as the group of the independent variable. Here the factor levels are High, medium and low, which also means that condition for the number of levels is also met.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1
