Luis saw graph that showed over 75% of Germans have been to more than 4 countries. Even more amazing, over 50% of Germans have visited more than 8 countries. Meanwhile, in the United States only 25% have been to more than 5 countries. Clearly Germans visit more countries then Americans. The researcher concludes that Germans are more adventurous then Americans.
· Do you have any concerns about the researchers statement? (Consider sample bias, Hawthorn effect, confounding variables, placebo effect)
· Is this an example of a misuse of statistics? Explain your reasoning.

The sharing economy is a fast-growing phenomenon. People increasingly share their home, car, clothing or tools on Internet platforms such as Uber, WeWork, and Airbnb. Statistics shows that there were 44.8 million adults using the increasingly popular sharing economy services in the United States in 2016. This figure was forecast to increase to 86.5 million by 2021. Choose a sharing economy based company, briefly describe the business model of the company, show the major costs of the company (please be specific and thorough), and discuss the major challenges faced by the company to reach break-even (please limit your answer to 600 words or less)

M/PF Research, Inc. lists the average monthly apartment
rent in some of the most expensive apartment rental locations in
the United States. According to their report, the average cost of
renting an apartment in Minneapolis is $951. Suppose that the
standard deviation of the cost of renting an apartment in
Minneapolis is $96 and that apartment rents in Minneapolis are
normally distributed. If a Minneapolis apartment is randomly
selected, what is the probability that the price is:
(Round the values of z to 2 decimal places. Round
answers to 4 decimal places.)
(a) $1,010 or more?
(b) Between $880 and $1,120?
(c) Between $825 and $935?
(d) Less than $730?

Confidence in banks: A poll conducted in 2012 asked a random sample of 1342 adults in the United States how much confidence they had in banks and other financial institutions. A total of 143 adults said that they had a great deal of confidence. An economist claims that less than14% of U.S. adults have a great deal of confidence in banks. Can you conclude that the economist's claim is true? Use both =α0.10 and =α0.01 levels of significance and the P-value method with the TI-84 Plus calculator.
(b) Compute the P-value. Round the answer to at least four decimal places.
P-value= ___

Suppose that Randy is an analyst for the bicyling industry and wants to estimate the asking price of used entry-level road bikes advertised online in the southeastern part of the United States. He obtains a random sample of n = 14 online advertisements of entry-level road bikes. He determines that the mean price for these 14 bikes is ¯¯¯ x = $ 714.19 and that the sample standard deviation is s = $ 184.56 . He uses this information to construct a 99% confidence interval for μ , the mean price of a used road bike. What is the lower limit of this confidence interval? Please give your answer to the nearest cent.
