The slope-intercept form of (-5,2) (-5,-1) is undefined
<u>Solution:</u>
Need to find the slope intercept form of line passing through two point (-5,2) (-5,-1).
Slope intercept form of line passing through is given by
On Substituting the values we get the slope intercept form of given points,
= undefined
Hence the slope intercept form of given points is undefined
Answer:
C. (n₁ + n₂ - 2) degrees of freedom
Step-by-step explanation:
The t-test for difference between two mean when variance are equal is:
where ,
= Mean of Sample 1
= Mean of Sample 2
s = standard deviation
n_1 = size of Sample 1
n_2 = size of Sample 2
and t is Student's t-test with (n₁ + n₂ - 2) degrees of freedom.
