How do SVMs handle the case of non-linearly separable data? (5 points) 

A product analytics team at a software company constructs a 95% confidence interval for the proportion of users who complete onboarding. Their current sample of n=400 users yields p^=0.55 and produces a total interval width of approximately 0.098. The team’s director wants to reduce this width to exactly half — approximately 0.049 — while keeping the confidence level fixed at 95%. Which of the following correctly identifies the required sample size change AND correctly explains why that specific change achieves the goal of halving the width?

Consider the three linearly separable two-dimensional input vectors in the following figure. Find the linear SVM that optimally separates the classes by maximizing the margin. The three points are (1,1.5), (0.5,1) and (1, 0.5). (10 points)  Hint: show and write the decision boundary and show the margin hyperplane H+ and H-.  

Once a weak classifier is picked in a particular round, it will never be chosen in any subsequent round.

A customer experience director at a subscription-based software company surveys 100 randomly selected current subscribers. The survey finds that 90 out of 100 customers (p^=0.90) report they would recommend the platform to a colleague. Using the Stats Kingdom calculator configured as a two-tailed proportion z-test with α=0.01, the output produces a 99% confidence interval of [0.8227, 0.9773] and a critical value of z*=2.5758. The director presents the following five conclusions about this confidence interval to the executive team. Select all statements that are TRUE.
