Answer:
An inference without a measure of reliability is nothing but a guess. The measure of reliability separates the science of statistics from the art of story telling. It gives a statistician a level of confidence that an inference made can to a reasonable extent be trusted
Step-by-step explanation:
Answer:
y = x - 3
Step-by-step explanation:
From the table attached,
Scatter plot given in the graph is correct.
Let the equation of the line passing from a point (x', y') is,
y - y' = m(x - x')
m = slope
Slope of the line passing through two points
and
is given by,
m = 
Therefore, slope of the line passing through the points (11, 8) and (12, 9) will be,
m = 
Therefore, equation of the line passing through (11, 8) will be,
y - 8 = 1(x - 11)
y = x - 11 + 8
y = x - 3
I'm pretty sure that it is 140. Hope I helped!
Answer:
The answer is 1.2
Step-by-step explanation:
It takes Rita 22.75 on average, and it take Erika 21.55 to walk the mile on average.
21.55 + 1.2 = 22.75
therefore, it takes Erika 1.2 minutes per mile less than Rita.
