1 answer:
Answer:
- 1. Figures are of same area
- 2. Figures are of different shape
Step-by-step explanation:
<em>See attached</em>
The figure in the graph is trapezium
1..................................................
The two shapes have an area of
<u>Triangle</u>:
- A = 1/2bh = 1/2*4*4 = 8 square units
<u>Rectangle:</u>
- A = wl = 2*4 = 8 square units
2..................................................
The two partitions are not identical in shape as one of them is triangle and the other is rectangle

Answer:
Therefore we fail to reject the Null hypothesis
Because the is no sufficient evidence to support the claim of the alternative hypothesis
Step-by-step explanation:
From the question we are told that
Sample size
Mean time 1
Mean time 2
Standard deviation
Standard deviation
Level of significance 0.05
The null hypothesis is
Alternative hypothesis
Generally the test statistics is mathematically represented as
From Table the Z-critical value at
Therefore
Zcal> Zcritical
(-0.43)=(-1.645)
Generally we fail to reject the null hypothesis at
Therefore we fail to reject the
Because the is no sufficient evidence to support the claim of
