There are a lot of strategies for setting up network defense systems. Physical restrictions can be put in place, such as separating hardware, or using switches and cabling to do so. One can also use virtualized segmentation in the form of VLANs, and virtual networks (including switches). What strategy do you feel is best suited to defend against modern cybersecurity threats? State your opinion concerning which technologies you would deploy if you were positioned to protect a university campus from cybersecurity threats. use any type of security, just need to know what is a strategy you would use that will defend against cybersecurity threats, and why? What is the best technology to use if I was to deploy one for a university?

Explain the procedure of creating a direction field (by hand) in your own words. Then explain how Euler's method works and why someone uses Euler's method. Your response should be about 250 words.

If acidic H2O2 is mixed with Fe^2+, which reaction occurs: the oxidation of Fe^2+ to Fe^3+ or the reduction of Fe^2+ to Fe? Give the balanced redox reaction for each possibility and explain your reason for selecting the reaction which will occur. Assume standard solution concentrations.

For a) I have:

red: H2O2 + 2H+ + 2e- ---> 2 H2O E=+1.78 V

oxi Fe2+ ----> Fe3+ + e- E=-0.77V

Ecell = 1.01V

I'm stuck on b) but for the explanation I think I understand that the one which is more positive is more thermodynamically favoured, but if I'm wrong on this I'd appreciate a pointer in the right direction.

1. A national newspaper reported that the state with the longest mean life span is Hawaii, where the population mean life span is 77 years. A random sample of 20 obituary notices in the Honolulu Advertizer gave the following information about life span (in years) of Honolulu residents.

(i) Use a calculator with sample mean and standard deviation keys to find x and s. (Round your answers to two decimal places.)

(ii) Assuming that life span in Honolulu is approximately normally distributed, does this information indicate that the population mean life span for Honolulu residents is less than 77 years? Use a 5% level of significance.

(a) What is the level of significance?
  

State the null and alternate hypotheses.

H₀: μ < 77 yr; H₁:  μ = 77 y

rH₀: μ = 77 yr; H₁:  μ > 77 yr    

H₀: μ = 77 yr; H₁:  μ ≠ 77 yr

H₀: μ = 77 yr; H₁:  μ < 77 yr

H₀: μ > 77 yr; H₁:  μ = 77 yr

(b) What sampling distribution will you use? Explain the rationale for your choice of sampling distribution.

The Student's t, since we assume that x has a normal distribution and σ is unknown.The Student's t, since we assume that x has a normal distribution and σ is known.     The standard normal, since we assume that x has a normal distribution and σ is known.The standard normal, since we assume that x has a normal distribution and σ is unknown.

What is the value of the sample test statistic? (Round your answer to three decimal places.)
  

(c) Find the P-value. (Round your answer to four decimal places.)

2. The Student's t distribution table gives critical values for the Student's t distribution. Use an appropriate d.f. as the row header. For a right-tailed test, the column header is the value of α found in the one-tail area row. For a left-tailed test, the column header is the value of α found in the one-tail area row, but you must change the sign of the critical value t to −t. For a two-tailed test, the column header is the value of α from the two-tail area row. The critical values are the ±tvalues shown.

Let x be a random variable that represents the pH of arterial plasma (i.e., acidity of the blood). For healthy adults, the mean of the x distribution is μ = 7.4†. A new drug for arthritis has been developed. However, it is thought that this drug may change blood pH. A random sample of 36 patients with arthritis took the drug for 3 months. Blood tests showed that x = 8.0 with sample standard deviation s = 1.7. Use a 5% level of significance to test the claim that the drug has changed (either way) the mean pH level of the blood. Solve the problem using the critical region method of testing (i.e., traditional method). (Round your answers to three decimal places.)

State your conclusion ion the context of the application.

Fail to reject the null hypothesis, there is sufficient evidence that the drug has changed the mean pH level.

Fail to reject the null hypothesis, there is insufficient evidence that the drug has changed the mean pH level.     

Reject the null hypothesis, there is insufficient evidence that the drug has changed the mean pH level.

Reject the null hypothesis, there is sufficient evidence that the drug has changed the mean pH level.

Compare your conclusion with the conclusion obtained by using the P-value method. Are they the same?

We reject the null hypothesis using the traditional method, but fail to reject using the P-value method.

The conclusions obtained by using both methods are the same.    

We reject the null hypothesis using the P-value method, but fail to reject using the traditional method.

State your hypothesis from Assignment 1.

I want my hypothesis to be hand washing related. What kind of hypothesis can I use to relate to this topic?

Why is this study important? Describe the rationale for your study, including the identified knowledge gap.  What is it that the health care industry does not know that will become clearer as a result of this study?

I also need a helping hand with getting it started using the questions above. If you can just assist with that I can do the rest.

Thank you

What value(s) should the decision be based on?

Government officials claim that no more than 29% of the residents of a state are opposed to building a nuclear plant to generate electricity. Local conservation groups claim that the true percentage is much higher. To test the government’s claim, an independent testing group selects a random sample of 81 state residents and finds that 29 of the people are opposed to the nuclear plant.

(a) What is the variable? Is it an attribute or measurable?

(b) State the hypotheses

(c) Calculate the value of the test statistic and the p-value?

(d) Would you reject H0 or fail to reject H0 at 5% level of significance?

(e) What would you conclude about the government’s claim?
