One sample from an independent-measures study has n = 16 with a variance of s2 = 65. The other sample has n = 25 and s2 = 70. What is the df value for the t statistic?

The answer is within reach for you young one

Step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
