Based on the QQ plots below, which statement best summarises how well the candidate distributions fit the completion_time data?

Question

Answer

All four distributions fit equally well, because the points in every plot follow a broadly upward trend.

Answer

The exponential distribution fits best, because its points span the widest range of theoretical quantiles.

Answer

The gamma and lognormal distributions are poor fits, because the few largest observations fall off the line.

Answer

The Weibull distribution fits best, because its upper-tail points lie furthest above the reference line.

Answer

The exponential distribution is clearly the worst fit, with systematic curvature away from the line, while the gamma and lognormal points lie close to the line across most of the range.
