| A computer company that recently introduced a new software product claims that the mean time taken to learn how to use this software is not more than 2 hours for people who are somewhat familiar with computers. A random sample of 12 such persons was selected. The following data give the times taken (in hours) by these persons to learn how to use this software. 1.90 2.20 1.75 2.25 2.40 1.50 2.75 2.15 2.25 1.80 3.25 2.60 Test at a 1% significance level whether the company's claim is true. Assume that the times taken by all persons who are somewhat familiar with computers to learn how to use this software are approximately normally distributed.
