Since there are no given sample statistics, Let us use the following: n=35, x=24.1, and o=2.7
2-tail test
Using a T-test:
t(24.1) = (24.1-23/[2.7/sqrt(35)] = -2.4103
P - value = 2*P(-100< t < -1.9720, when df = 34)
= tcdf (-100,-2.4103,34) -> using excel
= 0.0107
If you rearrange x - y = 2 into slope-intercept form,
x - y = 2
+ y
x = 2 + y
- x
0 = 2 + y - x
- 2
-2 = y - x
+ x
y = -2 + x
you get y = -2 + x, which means that the y-intercept is -2. I hope this helps!
Answer:
mean absolute deviation is <em>8</em>
Step-by-step explanation:
to find mean absolute deviation, you subtract your mean from each of your values, and make them all positive, (even if u get a negative..)
then you add all your new answers up and divide by how many numbers there are (basically just find mean of your new set of data...)

Answer:
only one has the value of -12
Step-by-step explanation:
like what
E) 12 minutes
A normal curve has approximately 95% of graph between mean - 2sd and mean + 2sd
So 95% of the times will be between 0 and 12 minutes. 6 - 2x3 to 6 + 2x3
2.5% will take over 12 minutes
Strangely 2.5% will also take less than 0 minutes to process which shows the normal curve is not perfect in this example.
