A different team of investigators then conducted a formal cost-benefit analysis of the above results. They aimed to establish a clinically meaningful absolute risk reduction for Prevenblu in populations at average risk of stomach ulcers. Using sound and appropriate methods, the investigators concluded that a clinically meaningful threshold for Prevenblu vs placebo would be an absolute risk reduction of 2% for the development of stomach ulcers. Using this threshold, apply the terminology presented in lecture (week 4) to the results of the trial of Prevenblu vs placebo. What can you conclude? (Select all that apply. You will check MORE THAN ONE box.) ? Prevenblu demonstrated a statistically significant reduction in stomach ulcers versus placebo after 1 year of treatment. When compared against the threshold of minimally important clinical benefit (a 2% reduction in the risk of stomach ulcer), the 95% confidence interval suggests that the findings are indeterminate (not precise enough). ? When compared against the threshold of minimally important clinical benefit (a 2% reduction in the risk of stomach ulcer), the 95% confidence interval suggests that the findings are negative. When compared against the threshold of minimally important clinical benefit (a 2% reduction in the risk of stomach ulcer), the 95% confidence interval suggests that the findings demonstrate a meaningful benefit. Because there was a statistically significant reduction in stomach ulcer risk, Prevenblu ought to be recommended (regardless of a threshold level of benefit).

Let \( X_{1}, \ldots, X_{n} \stackrel{i i d}{\sim} \operatorname{Ber}(p) \). We want to test \[ \begin{array}{l} H_{0}: \quad p \leq .5 \\ H_{1}: \quad p>.5 \end{array} \] at asymptotic level \( 5 \% \). Let \( \psi \) be the Wald test. 1) Assume that the true \( p \) is equal to 0.2 . What is the limit of \( \mathbf{P}_{0.2}[\psi=1] \) as \( n \rightarrow \infty \) ? \[ \lim _{n \rightarrow \infty} \mathbf{P}_{0.2}[\psi=1]= \] \( \square \) 2) For every \( \lambda>0 \) we can show that \[ \lim _{n \rightarrow \infty} \mathbf{P}_{.5-\frac{\lambda}{\sqrt{n}}}[\psi=1]=\mathbf{P}[Z>1.645+f(\lambda)] \] where \( f(\lambda) \) is a function that depends only on \( \lambda \). What is this function? \[ f(\lambda)= \] \( \square \)

A technician wants to measure the rate at which files are transferred in a local network. She defines a continuous random variable X as the time it takes to transfer a file between two computers in seconds. The technician discovers that X has the following PDF: \(f(t) = \begin{cases} at + b & \text{if } 0 < t < 4; \\ 0 & \text{otherwise.} \end{cases}\) In expectation, it takes 3.0 seconds to transfer a file between two computers. (a) Find $a$ and $b$ which make this a valid PDF. (b) Evaluate $Pr(X - 2 \le Var(X))$.
