A rainstorm in Portland, Oregon, has wiped out the electricity in about 7% of the households in the city. A management team in Portland has a big meeting tomorrow, and all 6 members of the team are hard at work in their separate households, preparing their presentations. What is the probability that none of them has lost electricity in his/her household? Assume that their locations are spread out so that loss of electricity is independent among their households.
Round your response to at least three decimal places.
The probability that none of them has lost electricity in his/her household is 64.7%.
ProbabilityGiven:
Electricity wiped =P=7%
Team members= n=6 members
Hence;
P(x = 0) = (6C0)(0.07^0)(1-0.07)^6
P(x = 0)= (1)(1)(0.93)^6
P(x = 0)=0.6469×100
P(x = 0)=64.7%
Therefore the probability that none of them has lost electricity in his/her household is 64.7%.

Around half of the electricity used in the United States is powered by burning coal. The United States is a developed country with a high level of carbon emissions. Select TWO realistic actions that could help to provide energy for the United States and also help to lower carbon emissions.
A
Create more fossil fuels.
B
Build additional power plants.
C
Reduce the demand for energy.
D
Use renewable sources of energy.
E
Make products that are more efficient.
F
Develop technology to better harvest fossil fuels.
The two options would be to reduce the demand for energy and or use renewable sources of energy. Options C and D are correct.
How to reduce carbon emissionThe burning of fossil fuels such as coal and crude oil-derived fuels generates a large amount of emissions.
In order to cut down on the emission, the demand for energy needs to be lowered by all means. In addition, instead of using fossil fuels, renewable sources of energy can be used.
Greenhouse gases such as carbon dioxide, oxides of sulfur, and water vapor are produced largely as by-products of burning fossil fuels. These gases form a layer in the atmosphere and trap reflected solar radiation.
By doing so, the increase the average annual temperature of the planet (global warming). The warming of the planet has several negative effects on the climate and the ecosystems as a whole.
Renewable sources of energy, on the other hand, have very little to no greenhouse gas emissions.

In a poll, 1002 adults in a certain country were asked whether they favor or oppose the use of "federal tax dollars to fund medical research using stem cells obtained from human embryos." Based on the poll results, it is estimated that 46% of adults are in favor, with a margin of error of 3 percentage points. Use the given statistic and margin of error to identify the range of values (confidence interval) likely to contain the true value of the population parameter
The range of values likely to contain the true value of the population parameter is from 43% to 49%.
What is Population parameter?This is referred to a statistical measurement for a particular population and is usually fixed.
We were told that the margin of error is 3 percentage points. This therefore means:
(46 ± 3) % = (46-3)% to (46+3)%
Therefore the range of values is 43% to 49%.

If warming trends continue, which of the following could happen to the glacial ecosystem? Choose ALL that apply.
A
Glacial runoff will begin earlier in the year, and as a result, streams will also warm earlier. Warmer streams will affect native fish populations.
B
Glacial melt and warmer temperatures will increase humidity levels in the ecosystem. This will decrease fish populations that thrive in colder climates.
C
Glacial loss will cool parts of the ecosystem, but because overall temperatures are warmer, precipitation will increase. Increased rain will raise stream and lake levels and increase fish populations.
D
Glaciers will melt into nearby bodies of water. The water levels will rise and create an overall cooling effect on the ecosystem, resulting in a net zero temperature change. The fish population will be unaffected.
E
Glaciers will melt into nearby oceans, causing the salt levels of the ocean to go down. This will increase the available habitat for fish and cause an increase in the nearby population.
If global warming trends continues, the options that could happen to the glacial ecosystem are;
"Glacial melt and warmer temperatures will increase humidity levels in the ecosystem. This will decrease fish populations that thrive in colder climates." (Option B)What is global warming?
Global warming is the name given to the occurrence of the continual melting of the ice cap and the negative effects that this can have on the earth.

It should be noted that the sample mean of the difference in temperature will be -0.34.
How to illustrate the information?From the information given, it should be noted that the difference in the temperatures given are -0.5, -0.6, -0.3, 0.1, -0.4.
It should be noted that d is the sample mean while s is the standard deviation.
Therefore, the sample mean of the difference in temperature will be:
= (-0.5 - 0.6 - 0.3 + 0.1 - 0.4)/5
= -1.7/5
= -0.34
The standard deviation of the difference in temperature will be 0.073.

How many liters each of a 50% acid solution and a 75% acid solution must be used to produce 90 liters of a 60% acid solution? (Round to two decimal places if necessary.)
The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
What is the litters about?Note that:
We take x = volume of 25% solution.
We take y = volume of 65% solution.
So, Equation of total volume:
x + y = 80
Hence the equation of amount of acid:
0.25x + 0.65y = 0.45(80)
0.25x + 0.65y = 36
Solve x + y = 80 for x.
x = 80 - y
Then Substitute into the second equation.
0.25(80 - y) + 0.65y = 36
20 - 0.25y + 0.65y = 36
0.4y = 16
y = 40
x + y = 80
x + 40 = 80
x = 40
Therefore, The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.

A researcher is interested in the effects of watching videos just before bed on the quality of sleep. He has decided to test the
claim "Watching 1 hour of video just before going to bed reduces the number of minutes of REM sleep by more than 10%. "
Which of the following data collection processes would be appropriate? Select only one answer choice.
Select the correct answer below:
Choose a random sample of people and ask them how many hours of video they watched last night and how much
REM sleep they had.
Choose a random sample of people. Randomly select half of them and have them watch one hour of video just
before going to bed, and then monitor their sleep. Have the other half not watch any video and monitor their sleep.
Choose a random sample of people. On multiple randomly selected nights, randomly assign each person to either
watch one hour of video or not watch video and monitor their sleep.
Choose a random sample of people. On multiple randomly selected nights, measure the amount of video they
watch and monitor their sleep.
The data collection process that would be appropriate would be Choice C: Choose a random sample of people. On multiple randomly selected nights, randomly assign each person to either watch one hour of video or not watch video and monitor their sleep.
Why is Random Sample the right answer?Choice C is the best option because it is a randomized controlled experiment, which is the gold standard for establishing causality.
In this design, the researcher randomly assigns individuals to either the experimental group (watching one hour of video before bed) or the control group (not watching any video before bed).
By randomly assigning individuals to the groups, the researcher can control for any preexisting differences between the groups and ensure that any observed differences in sleep are due to the intervention (watching video) rather than other factors.
Additionally, by measuring sleep on multiple nights, the researcher can control for any individual differences in sleep patterns and increase the generalizability of the findings.
