7.74 Beverage consumption. The results in the previous exercise were based on two national surveys with a very large number of individuals. Here is a study that also looked at beverage consumption, but the sample sizes were much smaller. One part of this study compared 20 children who were 7 to 10 years old with 5 37 to 19.9 oz. The authors state that the difference is statistically significant with P<0.01. information you would need to compute a confidence interval for the increase, and outline the procedure that you would use for the computations. Do you think that a confidence interval would provide useful additional information? Explain why or why not. children who were 11 to 13. day, while the older ones averaged 14.5 oz. The standard deviations were 10.7 oz and 8.2 oz, respectively. The younger children consumed an average of 8.2 oz of sweetened drinks per (a) Do you think that it is reasonable to assume that these data are Normally distributed? Explain why or why not. (Hint: Think about the 68–95–99.7 rule.) (b) Using the methods in this section, test the null hypothesis that the two groups of children consume equal amounts of sweetened drinks versus the two-sided alternative. Report all details of the significance-testing procedure with your conclusion. (c) Give a 95% confidence interval for the difference in means. (d) Do you think that the analyses performed in parts (b) and (c) are appropriate for these data? Explain why or why not. (e) The children in this study were all participants in an intervention study at the Cornell Summer Day Camp at Cornell University. To what extent do you think that these results apply to other groups of children?

Explain why does the peak emission wavelength of LEDs increase (red shift) with temperature? Why does the peak emission intensity decrease with temperature? Use sketches and curves for the answer.

According to the manufacturer of M&Ms, 13% of the plain M&Ms in a bag should be brown, 14% should be yellow, 13% should be red, 24% should be blue, 20% should be orange, and 16% should be green. A student randomly selected a bag of plain M&Ms. he counted the number of M&Ms that were each color and obtained the results shown in the table. Test whether plain M&Ms follow the distribution stated by M&M at the level of significance=0.05.

a) state the null and alternate hypothesis

b) verify the requirements

c) calculate the test statistic

d) find the corresponding p-value

e) state your conclusion

Explain in detail the following question:

Life will not be the same for any company which survives the cover-19 pandemic crisis. Organization will have to change and adapt.

Question: Select an organization which is likely to survive, in your opinion. How might it change? Describe 3 factors / levers which such an organization can use to promote change.   

Experimental Setup: Draw/describe how you will make voltage/current measurements in the lab using your orange multimeter (same device as last week).

1. Draw/describe how you will measure the voltage drop across a lightbulb in a circuit. Show/explain where you will put the black lead and the red lead from your orange multimeter and what setting you will have the device on to take this reading.

2. Draw/describe how you will measure the current through a lightbulb in a circuit. Show/explain where you will put the black lead and the red lead from your orange multimeter and what setting you will have the device on to take this reading. (Note: you will have to modify your circuit to make the current measurement because you need put the multimeter in the same wire path as the element through which you want to measure the current.)

Prelab 7: DC Circuits 1

What are the units of Resistance?

Watch the video tutorial about series and parallel circuits. Explain what ammeters and voltmeters do – Why are they hooked up to the circuit differently, and why don't they affect the circuit?

What is the resistance of a resistor when the colored bands read yellow, red, green and gold ?

What is a thermistor?

Three resistors with values of 1,488 Ohms, 1,101 Ohms and 860 Ohms are in parallel with each other in a circuit. What is the equivalent resistance of this parallel circuit?

Scenario: You are a loan officer for White Sands Bank of Sandia. Paula Jason, president of P. Jason Corporation, has just left your office. She is interested in an 8-year loan to expand the company's operations. The borrowed funds would be used to purchase new equipment. As evidence of the company's debt-worthiness, Paula provided you with "facts". 2019-10-20_1407.png Paula is a very insistent, some would even say pushy. When you told her you would need additional information before making your decision, she acted offended and said, "What more could you possibly want to know?"

Develop a minimum 700-word explanation, trying to get Paula as a bank client in the long run, of the financial statements and include the following: Explain why you would want the financial statements to be audited. Discuss the implications of the ratios provided for the lending decision you are to make. That is, does the information paint a favorable picture? Are these ratios relevant [Note: not all of them are] to the decision? State why or why not. Evaluate trends in the performance of P. Jason Corporation. Identify each performance measure as favorable or unfavorable and explain the significance of each. List three other ratios you would want to calculate for P. Jason Corporation, and in your own words explain in detail why you would use each. Based on your analysis of P. Jason Corporation, will you recommend approval for the requested loan? Provide specific details to support your decision.
