I am working on these questions but I would like someone to review them before I submit and add any addition information I may have missed or worse gotten wrong! I provided the questions and then my answers to them.
1) Explain what is blacklisting and whitelisting?
2) iptables:
Compare -j DROP vs -j REJECT. Which option would you use to implement a firewall rule that blocks incoming packets and why?
3) State the iptables command you would use to add a firewall rule where outgoing packets(connections) to ports 20, 21 (ftp) were blocked.
4) ICMP is a protocol for sending various messages to report network conditions. Ping is the sends ICMP Echo request packets to the target host and waits for ICMP echo reply from the host.
Your Task: State a firewall rule that will block other systems from pinging your system.
My answers.
1. Explain what is blacklisting and whitelisting?
White lists and black lists are two ways of filtering data. If you have a white list then you will filter in only data on the white list; if you have a black list you will filter out only data on that list.
2. iptables:
Compare -j DROP vs -j REJECT. Which option would you use to implement a firewall rule that blocks incoming packets and why?
Since DROP silently drops without a response, and REJECT denies and send an ICMP message to indicate the denial I think you would want to reject and never receive them to drop them using sudo ufw reject ssh
3. State the iptables command you would use to add a firewall rule where outgoing packets(connections) to ports 20, 21 (ftp) were blocked.
sudo firewall-cmd --direct --add-rule ipv4 filter OUTPUT 0 -p tcp --dport 20,22 -j ACCEPT
sudo firewall-cmd --direct --add-rule ipv4 filter OUTPUT 1 -j REJECT
4. ICMP is a protocol for sending various messages to report network conditions. Ping is the sends ICMP Echo request packets to the target host and waits for ICMP echo reply from the host.
Your Task: State a firewall rule that will block other systems from pinging your system.
sudo iptables -A INPUT -p tcp --dport 110 -j DROP
This doesn't not allow and connection to ping the system.

Describe in detail the reasons behind the two-way relationship between health and economic growth. Explain the factors for each side of the relationship between health and economic growth in detail in words. Please provide two factors for each side of the relationship, two that explain why better health results in higher economic growth and two factors of why higher economic growth can lead to better health.

You have spent a lot of time learning about the disgusting and heartbreaking effects of family violence, and you have learned much about societies response. This week you will also learn 2 strange consequences of that response; sex offenders being forced to live in the woods and an aggressive move by Boston Children’s Hospital to stop perceived abuse. What’s been developed is the question about how far is too far, and that’s what you’re writing about. Please about 600 hundred opinion paper stating your thought about how far the state should go to protect children. Is there a line they shouldn’t cross or does protection trump any other concerns? Be sure to support your thoughts with substantive criteria-no unsupported answers will be accepted. Also, include used references.

Parameter estimates:
intercept: 14179.871 3298.484 4.30 0.0003* (estimate Std Error tRatio Prob>t )
InCostAid: 0.7768753 0.254022 3.06 0,0058* (estimate Std Error tRatio Prob>t )
Baruch College has substantially less average debt compared to the other schools with similar in-state costs. Figure 10.13 contains JMP output for the simple linear regression of AveDebt on InCostAid with this case removed.
a) State the least-squares regression line.
b) The University of North Florida is one school in this sample. It has an in-state cost of $11,421 and average debt of $17,617. What is the residual?
c) Construct a 95% confidence interval for the slope. What does this interval tell you about the change in average debt for a $1000 change in the in-state cost?
ans:
a) y = 0.7768753InCostAid+14179.871
b) 0.7768*11421+14179.871 = 23052.5628
residual = 23052.5628 – 17617 = 5435.562801
c) 0.7768753+- t*0.254022 = 0.7768753+- 2.073873*0.254022 =
(0.2500659328, 1.303684667)
Baruch College was removed from this analysis because it was deemed an outlier. Let’s investigate its impact on the fit.
A) Refit the model using the entire sample of 25 schools. Create a table that summarizes the model estimates with and without this case.
B) Describe the impact this observation has on the fit of the linear regression model.
C) If you were writing a report for publication, would you include the fit with or without this case? Explain your answer.

INSTRUCTIONS: THERE ARE TWO SECTIONS IN THIS PAPER;
SECTIONS A AND B
ANSWER ALL QUESTIONS IN SECTION A AND ONLY ONE IN SECTION B
SECTION A
QUESTION ONE.
In a given economy, the following hold true.
1.There are only two sectors-household and business sectors
operating in the economy.
2. The percentage of every extra income which goes into consumption
is 80%.
Given that an initial amount of 1000 currency units is introduced
as investment in the economy. Draw up a table which tracks
successive expenditure, income consumption and savings in the
economy, up to the sixth round assuming the initial injection kicks
in a multiplier process.
Using your table, calculate the total amount of income and
consumption and deduce the value of the national income multiplier.
QUESTION TWO
Explain the difference between the criteria used to measure
absolute and comparative cost advantages in international trade.
Assuming there are only two countries in the world, Oceania and
Atlantis each having one resource unit which they use to produce
either Cereals or Machine tools and the table below depicts the
production possibilities of each country.
Maize (tons)
Machine Tools (Units)
Oceania

Determine which country has i. absolute cost advantage
ii. Comparative cost advantage.

You may believe that each day, married and unmarried women spend the same amount of time per week using Facebook. We would like to test this hypothesis. A random sample of 45 married women who use Facebook spent an average of 3.0 hours per week on this social media website. A random sample of 39 unmarried women who regularly use Facebook spent an average of 3.4 hours per week. Assume that the weekly Facebook time for married women has a population standard deviation of 1.2 hours, and the population standard deviation for unmarried Facebook users is 1.1 hours per week. Using the 0.05 significance level, do married and unmarried women differ in the amount of time per week spent on Facebook? State the decision rule for 0.05 significance level: H0: μ married = μ unmarried H1: μ married ≠ μ unmarried. (Negative values should be indicated by a minus sign. Round your answers to 3 decimal places.) Compute the test statistic. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.) What is the p-value? (Round your answer to 4 decimal places.) State your decision about the null hypothesis. Fail to reject H0 Reject H0
