Answer:
The slope is 25 and the y-intercept is 100
Step-by-step explanation:
With linear equations (y = mx + b), m<em> </em>is always the slope, which, in this case, is 25. It could also be written as , although it's not necessary here
B is always the y-intercept, which is 100 here
Answer:
2.104
Step-by-step explanation:
Data provided in the question:
For sample 1,
n₁ = 110
μ₁ = 94
s₁ = 14
For sample 2,
n₂ = 85
μ₂ = 72
s₂ = 15
Now,
Standard error =
or
Standard error =
or
Standard error = √4.43
or
Standard error = 2.104
