Jane the IE is notoriously tough on evaluations of time standards and rates people a bit harshly compared to her peers. She and Jim both audit Fred and come up with two different observations. She rates his pace at $85\%$ and Jim rates Fred at $95\%.$ They agree that Fred averages a part every $15$ seco

The Normal time is actually $13\mathrm{.}5$ minutes

The $5\%$ difference is negligible when PFD is applied

In one hour $$ Jane would expect $30$ more from the normal time operator than Jim would

In one hour $$ Jane would expect Fred to produce $30$ less than Jim.
