Let \( X_1, X_2, \dots, X_{10} \) be a random sample from a probability density function
\[
f_\theta(x) = f(x - \theta), \quad -\infty<x<\infty,
\]
where \( -\infty<\theta<\infty \) and \( f(-x) = f(x) \) for \( -\infty<x<\infty \). For testing
\[
H_0: \theta = 1.2 \quad \text{against} \quad H_1: \theta \neq 1.2,
\]
let \( T^+ \) denote the Wilcoxon Signed-rank test statistic. If \( \eta \) denotes the probability of the event \( \{T^+<50\} \) under \( H_0 \), then \( 32\eta \) equals
