We will consider statistical inferences for an exponential mean from Type I right censored data. Most inferential procedures developed so far are conditional in the sense that they can be used only when the number of observed lifetime data is at least one. One of our aims of the present article is to remove this restriction to allow zero observed frequency. An expression for exact unconditional probability calculus is given. Our second aim is to evaluate some approximate procedures by using the exact formula whether or not they give sensible numerical values.
