Statistics

The completion times for a job task range from 11.2 minutes to 19.6 minutes and are thought to be uniformly distributed.

What is the probability that it will require between 14.1 and 17.3 minutes to perform the task?

Please specify your answer in decimal terms and round your answer to the nearest hundredth (e.g., enter 12 percent as 0.12).

Suppose the variable x is represented by a standard normal distribution.

What is the probability of x > 0.3?
