Answer:
16 inches
Step-by-step explanation:
Given,
Perimeter = 72 inches
Breadth = 20 inches
Perimeter = 2 ( L+B )
72 = 2 ( L+20)
72= 2L + 40
72-40=2L
32/2=L
L=16 inches
therefore , lenght of the tile is 16 inches
The question requires stating the Null and Alternative hypothesis for the scenario described :
Answer:
H0 : μ = 24
H1 : μ < 24
Step-by-step explanation:
The claim or hypothesis to be tested in a statistical problem or analysis is the alternative hypothesis. This is usually the opposite of the Null hypothesis which is the usually the initial truth until there is significant evidence provided using statistical test to prove otherwise.
The null hypothesis, H0 in the scenario above is :
H0 : μ = 24 ( average battery life is 24 hours)
The alternative hypothesis is the claim, that is. The mean battery life not up to 24 hours ;
H1 : μ < 24
As we do not know the other cars avg speed we can not tell the answer. Please repeat the question.
