What is an element’s Atomic number tell you?

Matter is mostly empty space.

Can electricity flow in an open circuit?

The unit of Power is Watts (say what!?). The unit of Energy is Joules usually denoted by a J.

What are the different ways that light interacts with matter?

What is the speed of light in miles per second?

Light is both a particle and a wave. Light is also massless (I forgot to say in class)!

An automobile manufacturer claims that its van has a 26.3 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this van since it is believed that the van has an incorrect manufacturer's MPG rating. After testing 250 vans, they found a mean MPG of 26.7. Assume the variance is known to be 6.76. A level of significance of 0.1 will be used. State the hypotheses.

Ho:

Ha:

*Using the mpg column in the mtcars data conduct a hypothesis test to see if the true mean miles per gallon of cars is greater than 22. Use an alpha level of .1*

Please make sure you solve in R-studio. Solving without giving me R-codes will not help me. It would also help if you write a brief explanation of what you did. Thanks in advance!

The file Sedans contains the overall miles per gallon (MPG) of 2013 midsized sedans:

38,26,30,26,25,27,22,27,39,24,24,26,25,23,25,26,31,26,37,22,29,25,33,21,21

Source: Data extracted from "ratings," Consumer Reports, April 2013, pp. 30-31.

A) Construct a 95% confidence interval estimate for the population mean MPG of 2013 family sedans, assuming a normal distribution.

B) Interpret the interval constructed in (a).

C) Compare the results in (a) to those in Problem 8.20(a).

A water tower supplies water to a city through a pipe with 1 ft diameter. The pipe is 0.5 miles long and is made of commercial steel pipe. Over the years, the supply line lost head and engineers are considering the replacement of 94 percent of the pipe length with a larger diameter pipe (same type). The peak water demand is 3.53 ft3/sec. How much pressure head could be gained by this strategy?

Many individuals prefer to lease their vehicles rather than buy them. A new Cadillac CTSV can be leased for a down payment of $6,000 and 36 end-of-the -month payments of $599. Alternately, the car can be purchased for cash for $42,000 and a CTSV with about 60,000 miles is estimated to have resale value of $20,000 in three years from now. Should one lease or buy if opportunity cost is 6.36%APR?

SCENARIO OVERVIEW: Red Yoder is an 80-year-old farmer who lives alone in the farmhouse where he grew up. It is located 20 miles outside of town. Red has been a widower for 10 years. His son, Jon, manages the farm now, but Red is still involved in the decision making. Red is still involved in the decision making. Red's current medical problems include insulin dependent diabetes complicated by an open foot wound. Jon stopped by to check on Red after one of his friends from the VFW called to say that Red didn't make it for coffee. The nearest VA hospital is more than 100 miles away and the doctor told him that Red needed to be seen immediately. He is admitted for possible sepsis. Activities Required Prior to Simulation: Use textbook and other resources to answer questions:

1. What teaching is priority in the management of wound care for a diabetic client?

2. Describe the proper techniques to assess and care for a diabetic wound.

3. Identify the individual and environmental cues that can increase the risk for skin integrity issues in a diabetic client.

1. (2 pts) Hannah is an 18 year old female swimmer who’s primary stroke is the butterfly. Due to repetitive motion shoulder injury, she has been participating in physical therapy for the last 2 weeks. She has a BMI of 19 kg/m² and has no other orthopedic or heath issues. Based on your knowledge of the McGill’s Torso Endurance Test would this test be appropriate for Hannah? Provide details to support your answer.

2. (3pts) Miles is a 52 yo male who is a recreational triathlete. His BMI is 24.3 kg/m^2. He does not have any orthopedic or health issues. He is concerned about his overall core strength so you administer the McGill Torso Endurance test. His results are below.

1. (1.5 pts) Interpret Miles’ test results indicating what values are good versus poor.

2. (1.5pts) Identify what specific muscles could be contributing to the poor results from the results described in 2a.
