1. One Sample T-Test: Determine whether the average satisfaction rating of customers for a product is significantly different from a hypothetical mean of 75.
(Hints: The null can be about maintaining status-quo or no difference; If your alternative hypothesis is non-directional (e.g., μ≠75), you should use the two-tailed p-value from excel file to make a decision about rejecting or not rejecting null. If alternative is directional (e.g., μ < 75), you should use the lower-tailed p-value. For alternative hypothesis μ > 75, you should use the upper-tailed p-value.)
H0 =
H1=
Conclusion: The p value from one sample t-test is _______. Since the two-tailed p-value…
Decomposition geometry:
Mary is making a decorative yard space with dimensions as shaded in green (ΔOAB).Mary would like to cover the yard space with artificial turf (plastic grass-like rug). Mary reasoned that she could draw a rectangle around the figure so that the point O was at a vertex of the rectangle and that points A and B were on sides of the rectangle. Then she reasoned that the three smaller triangles resulting could be subtracted from the area of the rectangle. Mary determined that she would need 28 square meters of artificial turf to cover the green shaded yard space pictured exactly.
1. Matrix Operations
Given:
A = [ 33 ]A-[3-321]
-3
B = [342]B-[3-41-2]
(a) A² A2
Multiply A× A:
-3
=
(3 x 32x-3) (3 x 22 x 1)
| = |[19–63
|-9-3 -6+21] =
A² = 33 33 1-3×3+1x-3) (-3×2+1x1)
[12]A2=[3-321][3-321]=[(3×3+2x-3)(-3×3+1x-3)(3×2+2×1)(-3×2+1×1)]=[9-6-9-36+2-6+1
]=[3-128-5]
(b) | A ||A| Determinant of A
| A | (3 × 1) (2 x-3)=3+ 6 = 9|A|=(3×1)-(2x-3)=3+6=9
(c) Adjoint of A
Swap diagonal elements and change sign of off-diagonals:
A = [33], so adj (A) = |¯²]A=[3-321], so adj(A)=[13–23]
-3
(d) B-¹B-1
First find | B ||B|:
|B | (3x-2)- (1 × -4) = -6 + 4 = −2|B|=(3x-2)-(1x-4)=-6+4=-2
Then the adjoint of B:
adj (B) = [²
3
adj(B)=[-24-13]
Now,
B-1
1
=
|B|
· adj (B) = 1 [²¯¯³¹³] = [2₂ B
0.5
|B-1=|B|1-adj(B)=-21[-24-13]=[1-20.5-1.5]
2.
(a) Matrix Method: Solve
(2x + 3y = 6
(2x-3y=14
{2x+3y=62x-3y=14
Matrix form:
22 33-22
=
[223-3][xy]=[614]
Find inverse of coefficient matrix: Determinant:
| M | (2x-3) - (3 x 2) = -6 -6 = -12|M|=(2x-3)-(3×2)=-6-6=-12
Adjoint:
adj(M) = [3]adj(M)-[-3-2-32]
