Explanation Given info: In one survey RP Web sites were categorized as server-flow or client-flow Web sites. 20 were found to be vulnerable to an impersonation attack among 40 server flow sites. 41 were found to be vulnerable to an impersonation attack among 54 client flow sites. Calculation Let p 1 is the proportion of server flow sites that are vulnerable to an impersonation attack and p 2 is the proportion of client flow sites that are vulnerable to an impersonation attack. The hypotheses are given below: Null hypothesis: H 0 : ( p 1 − p 2 ) = 0 There is no significant difference between server flow sites and client flow sites that are vulnerable to an impersonation attack. Alternative hypothesis: H 0 : ( p 1 − p 2 ) < 0 There is sufficient evidence to say client flow sites that are vulnerable to an impersonation attack is likely than that server flow sites. Decision: If p -value< α then reject the null hypothesis H 0 . If p -value > α , then fail to reject the null hypothesis H 0 . Software Procedure: Step by step procedure to obtain p -value using the MINITAB software Choose Stat > Basic Statistics > 2 Proportions . Choose Summarized data . In First sample , enter Trials (n) as 54 and Events as ( x ) 41. In Second sample , enter Trials as 40 and Events as 20 Check Perform hypothesis test

A pandemic has begun and has been spreading in almost all countries. A tipster sent a handwritten letter to a military camp. According to the letter, the disease was due to a virus that a certain group of scientists made, and was initially developed to start a biological warfare among nations. A cure was also made alongside with it and showed that the disease may be controlled. Unfortunately, the cure was secured in a safe in a laboratory and is locked with a code. The safe was locked using the function: f (x) = 3z – 7 You are one of the troop tasked to divulge the code and open the safe. If this is the function used to lock the safe, what would be its inverse function? Write your complete solution in finding the inverse and upload a photo of this solution here.

2 Many students over the last couple of years have been earning money as social networking service influencers. The amount of influencers and their popularity has been growing steadily. The top 50 social networking service influencers have over 3 billion followers together. Unfortunately, this development has a downside for dogs. According to a recent newspaper article, dogs deemed less playful for video sharing social networking services are being dumped at shelters. The general perception of playfulness disproportionately affects older dogs. The accompanying table gives the data for a random selection of dogs from a local shelter for a correlation of age and days. Construct a 90% confidence interval to estimate the average number of days a dog that is 4 years old will stay at the shelter. Click the icon to view the data table. (CCECOP) Determine the upper and lower limits of the 90% confidence interval. UCL= days LCL = days (Round to two decimal places as needed.)

A PC board contains 205 components. Each component has the probability of not failing as 0.9996. All components are required not to fail if the PC board is not to fail. Each component is independent of all the others as far as failure mechanisms are concerned. Find (i) The probability of exactly one component failing (ii) The probability of the PC board not failing (iii) The probability of atmost one component failing
