# Question: Suppose that you have 15 observations on the number of

Suppose that you have 15 observations on the number of hours to failure of a unit. The observations are 259, 53, 536, 1320, 341, 667, 538, 1713, 428, 152, 29, 445, 677, 637, 696, 540, 1392, 192, 1871, and 2469. Is the exponential distribution a reasonable choice for the time to failure distribution? Estimate the MTTF.
