DATA SET G Mileage and Vehicle Weight Obtain the regression equation. (Negative amount should be indicated by a minus sign. Round your answers to 4 decimal places.) Calculate R2. (Round your answer to 4 decimal places.) Calculate the degrees of freedom and t-critical. (Round your answers to 2 decimal places.)Using the data set G, answer the questions given below. Solution Here dependent variable y is City MPG and indepedent variable x is weight. All the parts we can done by using MINITAB. Enter the data. STAT --> Regression --> Regression --> Response : y --> Predictors : x --> Results : select second option --> ok --> ok output is : Regression Analysis: y versus x The regression equation is y = 36.6 - 0.00456 x Predictor Coef SE Coef T P Constant 36.634 1.879 19.49 0.000 x -0.0045564 0.0004871 -9.35 0.000 S = 2.49891 R-Sq = 68.1% R-Sq(adj) = 67.3% Analysis of Variance Source DF SS MS F P Regression 1 546.44 546.44 87.51 0.000 Residual Error 41 256.03 6.24 Total 42 802.47 y = -0.00456 x + 36.6 R-sq is 68.1% or 0.681 Degrees of freedom is n-1. where n is number of data pairs. df = n - 1 = 43 - 1 = 42 And critical value by using EXCEL is, syntax : =TINV(probability, deg_freedom) where probability = alpha deg_freedom = df = 42 t-critical = 2.0181 We see that | t | = | -9.35 | = 9.35 t > t-critical Reject H0 at 5% level of significance. Conclusion : Population slope for x is differ than 0..

1. Define each class of incident.
types of incidents classifcations
repudiation
reconnaissance attack
harassment
extortion
pornography trafficking
organized crime activity
subversion
hoax
caveat

Solution
Incidents are classified based on their severity.Classification serves the purpose of taking the
proper action towards handling those incidents.The category of incidents whether it is related to
hardware or software or people and the type of incident stating whetherit is fault or failure etc are
to be taken into account.
Repudiation attack occurs when the system fails to take proper control of user's login
sessions.when this happens unauthenticated users or intruders pretending as authorized can easily
manipulate the data in the log fles or other important data.
Reconnaissance attack is a type of attack when an intruder attacks the system through varoius
ways like phishing spam mails ,malicious links etc aiming at gathering high confident
information from the user like bank account credentials.
Harrasment is making someone uncomfortable,degraded and humiiated with verbal or physical
behaviour in social or work environment which is a highly punishable offense in the present
society .
Extortion is forcing someone to give up something of value by threats or force against the will of
the person.Blackmailing is one such act.
Pornography Trafficking is using victim's illegal pictures or other media for promoting their
products in a commercial way exploiting the victim with out his/her consent.
Organized Crime involves clever ways of planning and plotting activities with the sole purpose
of making money simple.Some of them include hizacking,robberies ,scams etc
Subversion is an attack where by the heirarchy of file system is changed.Versioning is

2. maintaining a history of changes that are made to files .This is quite useful in data recovery.
Hoax attack provides wrong information to the user about viruses or some lottery or other social
messages making the ussers to respond to the particular mail.Aim is to delete important
information from the targetted system or to introduce malicious programs into the system.
Caveat is a warning about something which should be considered while doing an action.Like
messages warning the users about phishing while doing online bank transactions.
