An energy company wants to choose between two regions in a state to install energy-producing wind turbines. A researcher claims that the wind speed in Region A is less than the wind speed in Region B. To test the regions, the average wind speed is calculated for 90 days in each region. The mean wind speed in Region A is 13.8 miles per hour. Assume the population standard deviation is 2.8 miles per hour. The mean wind speed in Region B is 15.1 miles per hour. Assume the population standard deviation is 3.2 miles per hour. At alpha0.05, can the company support the researcher's claim? Complete parts (a) through (d) below.

As an engineer, you are asked to choose between a PV panel
system and a wind turbine for your site. PV panel system costs
1,000,000 USD to implement while the cost of the wind turbine
system is 600,000 USD. PV panels have a lifetime of 20 years, and
wind turbine lifetime is ten years. The annual operation and
maintenance cost of PV is 50,000 USD, and wind turbines are 30,000
USD. From the annual electricity generation, PV panels are making...

A natural gas energy company must choose between two mutually
exclusive extraction projects, and each costs $12 million. Under
Plan D, all the natural gas would be extracted in 1 year, producing
a cash flow at t = 1 of $14.4 million. Under Plan E, cash flows
would be $2.1 million per year for 20 years. The firm’s WACC is
13%.
a. Construct NPV profiles for Plans D and E, identify each
project’s IRR, and show the approximate crossover rate....

4. A steel producing company wants to compare between 2 types of
blends (A and B) to produce strong steel (based on the weight
capacity that can be supported). For this reason, an experiment was
carried out to produce steel from each mixture. Observed data are
load weights that can be supported, y. The results of the
experiment are summarized in the following table:
