When do creative people get their best ideas? USA Today did a survey of 966 inventors (who hold U. S. patents) and obtained the following information.
Time of Day When Best Ideas Occur
Time Number of Inventors
6 A. M.-12 noon 271
12 noon-6 P. M. 123
6 P. M.-12 midnight 327
12 midnight-6 A. M. 245
Required:
a. Assuming that the time interval includes the left limit and all the times up to but not including the right limit, estimate the probability that an inventor has a best idea during each time interval: from 6 A. M. to 12 noon, from 12 noon to 6 P. M., from 6 P. M. to 12 midnight, from 12 midnight to 6 A. M.
b. Do the probabilities add up to 1? Why should they?
