When do creative people get their best ideas? A newspaper 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 293 12 noon-6 P.M. 129 6 P.M.-12 midnight 325 12 midnight-6 A.M. 219 (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. (Round your answers to three decimal places.) 6AM - 12PM 12PM - 6PM 6PM - 12AM 12AM - 6AM (b) Do the probabilities add up to 1? ○ Yes. ○ No. Does this make sense? Examining the above table we find the table ---Select--- probabilities in the table ---Select--- the probabilities for all outcomes in the sample space. Therefore, the So, the above result ---Select--- ✓ make sense. What is the sample space in this problem? 6AM - 12AM ○ 6AM - 6PM O 12AM 12PM O the entire day
