Toyota is planning a new fuel cell powered car. It will cost $1.9 billion initially and an additional $0.6 billion the year after to build the factory, which can then be linearly depreciated to zero over 20 years, and be sold for $900 million at the end of year 21. The company also has to put up $80 million to buy components just before operation starts at the beginning of year 2. For each of the 20 years of operation...

In the year 2000, the average car had a fuel economy of 24.6 MPG. You are curious as to whether the average in the present day is greater than the historical value. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≤ 24.6, Alternative Hypothesis: μ > 24.6. If the true average fuel economy today is 39.2 MPG and the null hypothesis is rejected, did a type I, type II, or no error occur? Question 16 options: 1)...
