When a researcher needs to compare means for a variable grouped into two
categories based on some less-than interval variable, a t-test is appropriate.
To add, The analysis of two populations means through the use of
statistical examination is called a t-test. Small sample sizes commonly
use a t-test with two
samples. <span> What statisticians call as test statistics are
identified as t-values. A systematized value that is calculated from sample
data during a hypothesis test is called a test statistic. The procedure that
calculates the test statistic compares your data to what is expected under the </span>null
hypothesis<span>.
You already have an experience with the basic principles behind a t-test if you’ve
tried to communicated with a distracted teenager.</span>
I believe the answer is true
Answer:
I think 1/2 divided 1/2 is equal to 1
Step-by-step explanation:
I put in into the calculator and it said 1
{ y=-8x
{ y=-4-10x
Substitution Method:
-8x=-4-10x
x=-2
y=-8(-2)
y=16
(x,y) = (-2,16)
Check solution
{ 16=-8(-2)
{ 16=-4-10(-2)
{ 16=16
{ 16=16
Elimination Method:
{ 8x+y=0
{ 10x-y=-4
{ 8x+y=0
{ -10x-y=4
-2x=4
x=-2
8(-2)+y=0
y=16
(x,y) = (-2,16)
*For checking, its the same with the substitution method
