Answer:
yards = feet
Step-by-step explanation:
The graph is a straight line passing through the origin with equation
y = mx ( m is the slope )
Calculate slope using gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 2) ← 2 points on the line
m = =
=
the x- axis is feet and the y-axis is yards, hence
yards = feet
Answer:
We want a confidence of 99% so then the significance level would be 1%
The degrees of freedom are given by:
And the critical value using the significance level and
and the critical value would be:
Step-by-step explanation:
We know the following info :
represent the standard deviation from the sample
represent the sample size selected
We want a confidence of 99% so then the significance level would be 1%
The degrees of freedom are given by:
And the critical value using the significance level and
and the critical value would be:
