Answer:
(1) 330
(2) 692
(3) 110
(4) 43.25
Step-by-step explanation:
The data provided is for the dying time of four different types of paint.
One-way ANOVA can be used to determine whether all the four paints have the same drying time.
Use Excel to perform the one-way ANOVA.
Go to Data → Data Analysis → Anova: Single Factor
A dialog box will open.
Select the data.
Select "Grouping" as Columns.
Press OK.
The output is attached below.
The required values are as follows:
(1)
Sum of Squares of Treatment (Between Subjects):
SST = 330
(2)
Sum of Squares of Error (Within Subjects):
SSE = 692
(3)
Mean Squares Treatment (Between Subjects):
MST = 110
(4)
Mean Squares Error (Within Subjects):
MSE = 43.25
Answer:
From five given points it is find that points (1 , 1) and (4 , -1) will apply
Step-by-step explanation:
According to question,
Slop of line (m) =
And y-intercept is ( 0, )
So from above slope and points, the equation of line can be written as
y = mx + c
i.e =
x + c
=
(0) + c
= 0 + c
Or, c =
A) With points ( 5, )
At x = 5, y = (5) +
or, y = +
so, y =
Hence this points do not apply
B) With points ( 1 , 1 )
At x = 1, y = (1) +
or, y =
So, y =
y = 1
Hence this points will apply
C) With points ( 4 , -1 )
At x = 4 , y = (4) +
y =
y =
So, y= -1
Hence this points will apply
D) With points (-3 ,7)
At x = - 3, y = (-3) +
y =
Hence this point will not apply
E) with points (0 , 0)
At x 0, y = (0) +
Or, y = 0 +
y =
Hence this point will not apply
∴ From above five given points it is find that points (1 , 1) and (4 , -1) apply
