Some researchers developing a new intelligence test are trying to decide the maximum time to allow for completion of the test. The researchers have recorded the time for completion of the test for each of 28 participants who took the test for practice. The histogram below summarizes the completion time information for these 28 participants. Based on the histogram, estimate the mean time for completion (in seconds) for the participants. Carry your intermediate computations to at least four decimal places, and round your answer to at least one decimal place.
