Using your knowledge of supply curves, show the impact of the following changes on the respective supply curves:
An increase in construction workers’ wages on the supply curve for a new houses;
The development of a new pesticide on the supply curve for wheat;
The effect of a drought on the supply curve for corn; and
The effect of an increase in the price of shoes on the supply of shoes.

The construction estimator told the storage unit owner that building another section of storage units will likely add 100 more storage space renters to the bottom line. The rational storage business owner considered the rental prices of an additional 100 units, but he would decide to add more units if and only if

In a sample of 59 water specimens taken from a construction site, 22 contained detectable levels of lead. What is the upper bound for the 90% confidence interval for the proportion of water specimens that contain detectable levels of lead. Round to three decimal places (for example: 0.419). Write only a number as your answer.

238Pu decays to 234U via alpha () emission with a half-life of 87.7 years; each ejected alpha particle has an energy of approximately 5.6 MeV. Estimate the (thermal) power produced by the rover RTG immediately after the construction of the RTG (with ‘fresh’ 238Pu). State clearly the key assumptions in your analysis.

Explain in detail why is coordination required at all phases of construction for MEP systems? What are the outcomes when a job is not coordinated properly? Why is in important to coordinate at time of bid and what are the downsides to coordinating at the time of bid? Your response should include references to all MEP systems discussed during the semester.

Results of a survey revealed that the distribution of the amount of the monthly utility bill of a 3-bedroom house using gas or electric energy had a mean of $97 and a standard deviation of $12.
If the distribution of monthly bills can be considered mound-shaped and symmetric, what percentage of homes will have a monthly bill of more than $85 and less than $109?
If nothing is known about the shape of the distribution of monthly bills, what percentage of homes will have a monthly bill between $61 and $133?
If the distribution of monthly bills can be considered mound-shaped and symmetric, what percentage of homes will have a monthly bill of more than $121?
use Excel
explain how to calculate standard deviation and how you got the percentage?
