Answer:
a) H0: Time for first responders arrival is ≥ 8 min, Ha: Time for first responders arrival is < 8 min
b) Type I error: the arrival time is not greater than or equal to 8min
Type II error: the arrival time is greater than or equal to 8min
c) Type I error
Explanation:
a) the parameter of interest is the time of arrival of first responders. The hypothesis will test the time of arrival of first responders. The null hypothesis will be that it is greater than or equal to 8 min and alternate hypothesis will be that it is less than 8 min
b) Type I error: rejection of true null hypothesis
type II error: non-rejection of true null hypothesis
c) Serious setting would be in type I error as it would cause more damage
Answer:
The underclass of Americans
Explanation:
From the passage above, it can be deduced that those involved in drug trafficking in the united states is the underclass Americans. They are more so the ones actively involved and enjoying the gains of drug trafficking, on the other hand with the law enforcement agencies, they are risking there lives in arresting the drug traffickers ,there is no way they can say drug trafficking has a useful place in the society because people are risking there lives to stop it, apart from the fact that there ate drug traffickers, the consumers on the other hand are involved which is causing more problems in the society that creating a useful place so it is the underclass Americans involved in the drug trafficking are the ones more likely to say there drug trafficking has a useful place in the society based on the passage.
Answer:
James-Lange theory
Explanation:
According to ames-Lange theory emotion results from physiological states triggered by stimuli in the environment. Essentially, the theory proposes that after the initial perception of a stimulus, the experience of the emotion results from the perception of one's own physiological changes that is changes in heart rate, breathing, and sweating patterns. For example you are walking down the alley late at night. You hear footsteps behind you and you begin to tremble, your heart beats faster, and your breathing deepens. You notice these physiological changes and interpret them as your body's preparation for a fearful condition
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Indeed, global warming has been in the foreground of politics and science for quite some time. There have been numerous studies conducted on the effects of global warming and what we might do to mitigate any threats. I think some policymakers are wary of the findings and some can trust that the conclusions are sound for the following reason.
Politicians are wary because, in reality, there are no 100% conclusive arguments that confirm that global warming is the result of humans. For other politicians, the evidence provided by environmental institutions is valid and they are prompt to proclaim that humans are to blame for global warming.
What is real, is that earth scientists think that global warming caused significant climate change in the past. And when they say the past, they mean a time before humans appeared on planet earth.
Climate change or global warming is not new for planet earth. It is a phenomenon that has happened in the past according to scientists and national agencies. It is believed that global warming had caused natural disasters such as the melting of ice caps and the flooding of many lands on Earth, destroying life forms.
That is why right now, many agencies are closely researching climate change. Among those institutions are the US National Academy of Sciences, the Geological Society of America, the American Meteorological Society, and the National Aeronautics and Space Administration.
