8/10 is the fraction can be read as 8 out of 10.
So, in order to represent it visually, we can make a circle first.
Then divide the circle 10 identical parts.
As given fraction is 8 out of 10, we need to shade 8 parts out of all 10 parts.
That shaded portion would represent fraction 8/10.
I have attached a diagram.
The circle is divided into 10 identical parts and I shaded 8 parts of it by red color.
That red colored shaded portion represents 8/10.
Answer:
1.
The null hypothesis
H0: Ud=0
The alternate hypothesis
H1:Ud≠0
2. Test statistic = -3.04
3. P value = 0.039
4. Reject h0
Step-by-step explanation:
X = right arm
Y = left arm
d = difference between both arms
X. Y. d(x-y). d²
145. 173. -28. 784
142. 163. -21. 441
116. 182. -66. 4356
133. 148. -15. 225
134. 149. -15. 225
Total
d = -145
d² = 6031
We have sample space n = 5
d' = -145/5
= -29
Sd = √1/n-1(Σd²-(Σd)²/n
Sd = √1/4(6031-(-145)²/5
= √1/4(6931-4205)
= √456.5
= 21.366
To get t
=d'/(sd/√n)
= -29/(21.366/√5)
= -3.035
In summary
This is a two tailed test
1.
The null hypothesis
H0: Ud=0
The alternate hypothesis
H1:Ud≠0
2. Test statistic = -3.04
3. P value = 0.039
4. We have pvalue to be 0.039 which is less than the level of significance 0.05
0.039<0.05, so we take decision to reject h0 which is the null hypothesis
We have enough evidence to support claim that there is a measurement difference between left and right arms
Expression: <span>t=2(2h/32)^1/2
Squaring on both sides,
t</span>² = 2(2h/32)
t² = 4h/32
t² = h/8
h = 8t²
Height of player 1 = 8(0.9)² = 6.48 Feet
Height of player 2 = 8(0.8)² = 5.12 Feet
Difference = 6.48 - 5.12= 1.36 Feet = 16.32 in
In short, Your Answer would be:16 Inches
Hope this helps!
