1. A stochastic process {X(t), t > 0} has the one-dimensional distribution

Is this process weakly stationary?

2. The one-dimensional distribution of the stochastic process {X(t), t > 0} is

With μ > 0, σ > 0; x ∈ (−∞ + ∞).

Determine its trend function m(t) and, for μ = 2 and σ = 0.5, sketch the functions
