Answer:
<u>Alternative hypothesis 1</u>: the mean amperage at which the fuses burn out is > 40 amperes.
<u>Alternative hypothesis 2</u>: the mean amperage at which the fuses burn out is < 40 amperes.
Step-by-step explanation:
Recall that the null hypothesis is the fact you want to refute and is in doubt.
So, in this specific case, <em>the null hypothesis would be that the mean amperage at which the fuses burn out is 40 amperes.
</em>
The alternative hypothesis are those that want to refute the null hypothesis, in this case there are 2:
<u>Alternative hypothesis 1:</u> the mean amperage at which the fuses burn out is > 40 amperes.
<u>Alternative hypothesis 2:</u> the mean amperage at which the fuses burn out is < 40 amperes.
Answer:
<h2>d≈7m</h2>
C Circumference
22 m
Using the formulas
C=2πr
d=2r
Solving ford
d=C/π=22/π≈7.00282m
Step-by-step explanation:
Hope it is helpful.....
Answer:
75.36 feet
Step-by-step explanation:
The formula for circumference is C=2xpixr. Diameter is two times the radius so the radius is 12 feet. If we plug everything in, then 2 times pi equals 6.28 times 12 equals 75.36 feet.
