A medical statistician wants to estimate the average weight loss of people who are on a new diet plan. In a study, he guesses that the standard deviation of the population of weight losses is about 20 pounds. How large a sample should he take to estimate the mean weight loss to within 8 pounds from the sample average weight, with 95% confidence? Is your estimation always correct? Please briefly explain your reasoning. If you start with a bigger sample, (under the condition that the confidence level and standard deviation remain unchanged,) then does it affect the accuracy of the estimation? Please briefly explain your reasoning. What happens to the confidence interval if the standard deviation takes a bigger value? Please briefly explain your reasoning.

you decide to do something about the problem underlying the current epidemic of obesity and diabetes. You design a drug that protects your organism from the toxic effects of fructose. Assuming your drug interferes with each of three processes: digestion, absorption and assimilation (metabolism), explain what fructose-specific mechanisms are inhibited/altered. Make sure your wonder-drug does NOT block uptake of glucose by cells

1. What is a 'technology dead end’? Why are technology dead ends important for economic growth? Illustrate with an example. Hint: Easterly (2002) talks about all this in ch. 9.
2. In your opinion, does intellectual property (i.e. temporary ownership of ideas) incentivize the creation of more new ideas or does it lower the rate of subsequent innovation and creative expression? Explain briefly how or why. Gilbert (2011) may help you think about this.

How important is it to trace costs appropriately? Explain.

As you are beginning to think about the importance of tracing costs appropriately, please consider the differences between variable costing and absorption costing. What implications does each of these have on such things as financial reporting of profit and pricing your products for the marketplace?

You may also want to think about the issues involved with traceable costs as discussed in our text or in articles that you may find online.

MATLAB, if-else

Write a script which to do the following. Take an array of any size as input and check if all the elements are integers. (i) If not, display the error message ‘Invalid input!’. Use the error command to create a proper error message in red. (ii) If yes, count the number of rows where the sum of the elements is smaller than the average row sum. It is recommended that you use a test variable with many rows (> 10 ).
