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
Answer:
<u>A</u>
Step-by-step explanation:
1.) add
2.) and
If you look at the chart you can see when you add B and D it equals E, therefore your answer is add.
Answer:
=5(9)+6+1. =45+7 =52
=52.move the x with the negative exponent into the denominator and change the sign. 1,3x'y+2xy-5y.solve when x = - 2;y = 3
Step-by-step explanation:
Answer:
A cyclist can travel 18 kilometres in 1.5 hours.
Step-by-step explanation:
The ratio for the cyclist's speed is 12 km/1 hr. If I were to find the ratio for kilometres per 1.5 hour, I would need to multiply the denominator of 1 (aka 1 hour) by 1.5 to get (1.5 hours). Whatever you do to the bottom, you have to do to the top. So I multiply the numerator of 12 (12 km) by 1.5 to get 18 km.
12 km/1 hr → 18 km/1.5 hrs
