write my assignment 13617

A professor is interested in comparing the average amount spent on textbooks for freshmen and sophomores. A random sample of 8 freshmen yielded a sample mean amount of $1013 and a sample standard deviation of $75. A random sample of 8 sophomores yielded a sample mean amount of $1234 and a sample standard deviation of $340. Construct a 99% confidence interval for the difference between the mean amount spent on textbooks by freshmen and the mean amount spent by sophomores (ie. do freshmen minus sophomores). Since the sample standard deviations are wildly different, use a method which does not assume the populations have the same variance.# (1 pts)What is the appropriate degrees of freedom in this case? Give your answer to four decimal places.Response: # (1 pts)What is the lower confidence limit on the interval? Give your answer to two decimal places.Response: # (1 pts)What is the upper confidence limit on the interval? Give your answer to two decimal places.Response: # (1 pts)Using this interval, is it reasonable to conclude that the average sophomore spends more than the average freshman? Yes because the upper endpoint on the interval is below 0. Yes because the upper endpoint on the interval is above 0. No because the interval contains 0. Yes because the interval contains 0.

a)Go to https:// (https:// and review the information on how to research and analyze tariff data. Then, navigate to the Get tariff data page https:// (https:// Based on your chosen country (Week 1 discussion- PANAMA), use the Get tariff data page to determine the kind of footwear you wish to import into the country, and identify the appropriate tariff(s) you will pay. Discuss the amount of the tariff you will have to pay.

b)Suppose you are five (5) years into exporting shoes to your chosen country (PANAMA) , and have decided to try a new global strategy. Compare and contrast licensing and investment in general, and select one (1) for your new strategy. Support your decision with a rationale.

3) It’s common knowledge that labeling has become global. Examine the labeling regulations that your chosen country has (PANAMA). Give examples of at least two (2) labeling regulations that benefit consumers. Select one (1) of these regulations and review its effect on manufacturers, suppliers, and distributors, as it relates to your importing of shoes into your country (PANAMA).

Can someone check my work again to see if i done this right: thank you

hypothesis test

The hypothesis scenario:

A doctor wants to know if the median BMI of a group of 100 patients with presumed overweight is equal to 30. (this is the medical value to know if you are overweight) Given the sample mean of 31.

Based on historical data, the doctor knows that these patients have a standard deviation of 5, so he uses this value as the standard deviation of the population in a Z test of 1 sample.

My explanation:

Null hypothesis H0: μ =30

Alternative Hypothesis H1; μ >30

You can put this in calculator

(31-30)/(5/√100)

=2

1-Norm.dist(2, true)

=0.02275

Norm.s.inv

=0.9772

Using the Z to P value calculator with α =0.05 and z=2, you get 0.9772

P value= 1−0.9772=0.0228

The P-value is significant at 5% and thus the null hypothesis is rejected at that point. We conclude that at 5% significance level, μ >30

Socrates, whom many believed to be the first great philosopher, while also agreed that the soul was separate from the brain and that it did survive physical death did not believe that its basis was religion and perceived to on more rational grounding. He believed that the soul or the part of a human that actually thinks and feels is immortal, which again is similar to what those with religious standings believe. His most plausible reasoning behind this is quite simple. For something to be destroyed it would have to be able to be broken down, but the soul has no parts that can be detached from one another and that because the soul is not a physical thing it cannot be burnt, crushed, or mangled, therefore it can not be destroyed (Rachels 2012).

           There are plenty of objections to the possibility of there being a soul. Science, for instance, would have pointed to a definite no. There is Scientist who has relentlessly studied the brain. They have developed techniques to even map the brain and thought patterns with brain-imaging. One such essay that argues there is no soul, wrote by Stephen Cave, called Argument Against the Soul, believes that there isn’t a soul because people that have experienced brain damage or permanent brain loss, such as Alzheimer, causes individuals to act completely different than they once were. To me, that argument seems flawed though. Take a car for instance, if the motor fails or becomes irrevocably damaged does it stop being a car? It will not run properly and may not even function at all but at the end of the day, it’s still a car. Perhaps its that we simply do not have the technology to fully understand the body and mind. After all, it was only a few hundred years ago that majority of the world believed it to be flat.
