This case study is about a study on coffee consumption of people that live in the United States. In total, 92 people were randomly selected and data was gathered regarding the annual consumption of coffee in gallons. Of these 92, 51 were females and 41 were males.

Of the 92 people in the sample, the annual consumption of coffee and the weekly amount of hours worked were compared to find r = 0.623. Test the significance of this correlation coefficient using ? = 0.01.

4. A consumer group claims that the mean annual consumption of coffee by a person in the United States is 25 gallons. A random sample of 100 people in the United States has a mean annual coffee consumption of 22.5 gallons. Assume the population standard deviation is 4.8 gallons. At ? = 0.05, can you reject the claim? Be sure to set up your hypothesis test, solve using the p-value, and interpret your results

In a long-term study about coffee consumption, age, and memory, a researcher gathered N=10 participants. The researcher gave the participants a list of words to remember, and asked them how many of these words can be recalled 2 hours later. On day 1, participants were told to come in, but refrain from drinking any caffeinated drinks at least 24h prior to the testing session. On day 2, participants were told to come in, and consumed one cup of coffee prior...

Do left-handed people live shorter lives than right-handed people? A study of this question examined a sample of 949 death records and contacted next of kin to determine handedness. Note that there are many possible definitions of "left-handed." The researchers examined the effects of different definitions on the results of their analysis and found that their conclusions were not sensitive to the exact definition used. For the results presented here, people were defined to be right-handed if they wrote, drew,...

Assignment 2-Case Study-Chapters: 7, 8, 9 & 12 (Macroeconomics) ECON201 Case Study When taxes induce people to change their behavior—such as inducing Jane to buy less pizza—the taxes cause deadweight losses and make the allocation of resources less efficient. As we have already seen, much government revenue comes from the individual income tax in many countries. In a case study in Chapter 8, we discussed how this tax discourages people from working as hard as they otherwise might. Another inefficiency...
