The accompanying data resulted from a flammability study in which specimens of four different fabrics were tested to determine burn times. Fabric Type Ýi. Si ni 1 11.6 .75 42 13.1 .88 43 14.5 .94 44 15.6 .98 4The analysis of variance is given as follows: Source DF SS MS F p-value Fabric Type 3 28.322 9.441 11.875 0.002 Error 12 9.543 0.795 Total 15 37.865 A) Write a linear contrast for Question 1: Is the mean burn time of fabrics of type 3 different than the mean burn time of type 4? B) Write a linear contrast for Question 2: Is the mean burn time of fabrics of type 1 different than the average of burn times of fabrics of the other three types (2, 3, 4)? C) Are the two contrasts defined in (a) and (b) mutually orthogonal? Explain why or why not. D) Conduct a F test about the linear contrast defined in (a). Use a = 0.05
Answer:
Following are the solution to the given point.
Step-by-step explanation:
In point a:
Linear comparison of the mean burning period of textiles of type three different from the mean type 4 burn time:
[tex]\to C_1= \bar{y_3}- \bar{y_4}[/tex]
In point b:
Linear comparison to the moderate burning time of type 1 textiles distinct from the average burn periods of all the other three styles of textiles[2,3,4]: is
[tex]\to C_2 = \bar{y_1} - \frac{1}{3} \bar{Y_2} - \frac{1}{3} \bar{Y_3} - \frac{1}{3} \bar{Y_4}[/tex]
In point c:
The comparison in a and (b) above is orthogonal to one another. Since the number of coefficient products is :
In point d:
The contrast value is [tex]C_1 = \bar{y_3} -\bar{y_4}.[/tex] The estimate of the contrast:
[tex]=14.5-15.6\\\\=-1.1[/tex]
The standard error is
[tex]= \sqrt{0.795 \times \frac{2}{4}}\\\\ = \sqrt{0.3975}\\\\= \sqrt{0.6305}[/tex]
[tex]t= \frac{(\bar{y_3} - \bar{y_4})}{SE(\bar{y_3} - \bar{y_4})}= \frac{-1.1}{0.6305}= -1.7447[/tex]
T is 2.1788 as the critical value. Since the value of t=1.7447<th of the critical value is absolute, the null is not rejected
The hypothetical one. theory. Therefore the impact of contrast is not statistically significant.
As we know t is a test F. Alternatively, as we know. The F-statistics at 1,12 df is [tex]t^2 = -1.7445^2 = 3.0440.[/tex]
F test is critical to 4,7472.

Which statement explains whether -4.5 can be a value in the shaded region
A. No it cannot, because -4.5 lies to the right of -3.5
B. No it cannot, because -4.5 lies to the right of -3.5
C. Yes it can, because-4.5 lies to the left of -3.5
D. Yes it can, because -4.5 lies to the right of -4.5
Answer:
Option C is correct option.
Step-by-step explanation:
The option C : Yes it can, because-4.5 lies to the left of -3.5 is the correct option.
Reason:
-4.5 is less than -3.5 and it comes after -4 so it lies under the shaded region.
Option C is correct option.

What is the equation of the line that passes through the point (-4,-8) and has a slope of 4
Answer:
y=4x+28
Step-by-step explanation:
(y-y1)=m(x-x1)
(y +4) = 4(x+8)
y+4 = 4x+ 32
y=4x + 28

For the set (1, 1, 2, 4, 5, 6, 7, 8, 10),
would each of the following measures be affected if another value of 10 was
included?
A. The range
B. The mean
C. The median
D. The mean and median
Answer:
it could be the mean median
Answer:
D the mean and median
Step-by-step explanation:
it would affect the mean because you have to add another number and the number of terms would change.
it would affect the median because the middle number would change since there is one more term.

Answer:
43.95963871
Step-by-step explanation:
I used the tangent. Tangent is opposite over adjacent sides. To set it up, tan(7)=opp/16
move around to get opp=(16)tan(70)
opp=43.95963871
nearest whole height= 44 ft
Step-by-step explanation:
Step 1: List out all of the formulas for the trigonometric functions
sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent
Step 2: Find the equation for h
tan(70) = h / 16
16 * tan(70) = h
Step 3: Solve for h
h = 16 * tan(70)
h = 43.9596
h = 44 ft
Answer: 44 ft
