Med Student Sleep Average (Raw Data, Software Required):
Here we consider a small study on the sleep habits of med students and non-med students. The study consists of the hours of sleep per night obtained from 30 non-med students and 25 med students. The sample data is given in the table below. Test the claim that, on average, the mean hours of sleep for all med students is different from that for non-med students. Test this claim at the 0.01 significance level.



(a) The claim states there is a difference between population means (μ1μ2 ≠ 0). What type of test is this?

This is a two-tailed test.

This is a right-tailed test.   

This is a left-tailed test.


(b) Use software to calculate the test statistic. Do not 'pool' the variance. This means you do not assume equal variances.
Round your answer to 2 decimal places.

t =



(c) Use software to get the P-value of the test statistic. Round to 4 decimal places.
P-value =

(d) What is the conclusion regarding the null hypothesis?

reject H0

fail to reject H0    


(e) Choose the appropriate concluding statement.

The data supports the claim that, on average, the mean hours of sleep for all med students is different from that for non-med students.

There is not enough data to support the claim that, on average, the mean hours of sleep for all med students is different from that for non-med students.    

We reject the claim that, on average, the mean hours of sleep for all med students is different from that for non-med students.

We have proven that, on average, the mean hours of sleep for all med students is different from that for non-med students.

Create an excel workbook for the following questions. Answer these questions under your Solver work for each respective problem.

1. Devos Inc. is building a hotel. It will have 4 kinds of rooms: suites where customers can smoke, suites that are non-smoking, budget rooms where the customers can smoke, and budget rooms that are non-smoking. When we build the hotel, we need to plan for how many rooms of each type we should have. The following are requirements for the hotel:

  1. We want to figure out how many rooms of each type to build based on maximizing revenue if we fill up the hotel. We expect to charge $190 for a suite that is non-smoking and $140 for a budget room that is non-smoking. Smoking room customers for both suites and budget rooms will have to pay an additional $20 per night.
  2. We can spend up to $7,500,000 on construction of our hotel. The cost to build a non-smoking budget room is $12,000. The cost to build a non-smoking suite is $15,000. It is $3,000 additional for a smoking room of either type for smoke detectors and sprinklers.
  3. We require that the number of budget rooms be at least 1.5 times the number of suites, but no more than 3 the number of suites.
  4. There needs to be at least 80 suites, but no more than 200.
  5. Industry trends recommend that smoking rooms should be less than 50% of the non-smoking room and in addition, we require our builder gives us at least 4 smoking rooms.

Answer the following using your Solver answers:

  1. How many of each room type should be built, and what would the revenue be for a night when our hotel was fully booked?
  2. Without re-running Solver, what happens to our revenue if we get an additional $1,500,000 for building? Explain in words how you got this answer without re-running solver. Over what amount of construction costs can you use this procedure?
  3. Over what range of room price can our budget non-smoking rooms vary over for us to get the same answer for the quantity of each type of room?

A BUG AGAINST OBESITY. The fastest spreading illness in the developed world is obesity.

 

A BUG AGAINST OBESITY. The fastest spreading illness in the developed world is obesity. While willpower and nutrition choices are certainly important for controlling obesity, increasing evidence supports the hypothesis that elements of the microbiome are also important. Using synthetic biology approaches, develop a "probiotic" bacterium that can safeguard against obesity. You may use one of two approaches. First, you can design an organism that will consume excess calories, leaving only the appropriate amount for the host. In this case, make sure to take into consideration the fact that the host also needs a number of other nutritional factors -- N, P, Fe, vitamins -- and the bacterium must make sure to leave these behind as it consumes "calories". The second approach is to design a bacterium that will target and kill specific strains of bacteria known to enhance obesity -- mostly enteric Firmicutes (e.g. "Gram-positive" bacteria). These bacteria must be able to both FIND (by swimming towards them) and KILL these bacteria with specificity -- i.e., they leave all the other "normal flora" intact.

****Instructions:

  1. Don’t say anything factually wrong. Speculation is okay, but point out when you’re speculating and justify your speculation with facts.
  2. Don’t say anything irrelevant. (i.e., don't throw up everything you can think of hoping some of it will stick)
  3. Provide justifications for every non-obvious point. Citations are helpful – especially to things in your textbook that I can easily look up!
  4. Make sure your answers proceed logically and that you have a clearly stated thesis or hypothesis that is supported by evidence that’s appropriate to the question.
  5. Use "normal language" as much as possible -- avoid "big sciency words" especially if you think there's any chance I will question whether you know what they mean. In other words, don't vacuum up material from the internet and put it into your answer.
  6. Don’t write more than 1500 words. If you’ve got more than that, consider using drawings and other types of figures to get rid of some words.
