A manufacturer of electronic kits has found that the mean time required for novices to assemble its new circuit tester is 3 hours, with a standard deviation of 0.20 hours. A consultant has developed a new instructional booklet intended to reduce the time an inexperienced kit builder will need to assemble the device. In a test of the effectiveness (greatness) of the booklet, 15 novices require a mean of 2.90 hours to complete the job. Assuming the population of times is normally distributed, and using a 0.05 level of significance, should we conclude that the new booklet is effective? Determine and interpret the P-value for the test.
