Q6 You have two machines. Machine 1 has a lifetime T which is exponentially distributed with parameter d1, andMachine 2 has a lifetime T, which is exponentially distributed with parameter A, and is independent of T1. Machine1 starts at time 0, and Machine 2 starts at a time T > 0.Q6(i.) Assume that T is deterministic. Compute the probability that Machine 1 is the first to fail.Q6(ii.) Answer the same question when T is exponentially distributed with parameter u and is independent of T1and T,.

Consider the following model: y = ß0 + ß1x + ε . In this model, the following is true: a) there is a deterministic component and a random component in the model equation b) the error term in the model represents cumulative mistakes made by the researcher in computing his/her statistics on the sample c) the intercept value is necessarily equal to 0 for any sample on which this equation is applied (as evidenced by the fact that it is indicated by the subscript 0) d) when computed on a sample, the slope must always be positive for this equation to work e) if we were to use this equation for prediction, we’d place “hats” above certain values in the equation f) a and e g) a, b and e
