Question: Suppose that y 1 , y 2 , . . . , y n is a random sample of size n from a normal distribution

Suppose that y₁, y₂, . . . , y_n is a random sample of size n from a normal distribution where σ is known. Depending on how the tail-area probabilities are split up, an infinite number of random intervals having a 95% probability of containing μ can be constructed.
