A problem with a telephone line that prevents a customer from receiving or making calls is upsetting to both the customer and the telephone company. Samples of 6 problems reported to two different offices of a telephone company and the time to clear these problems (in minutes) from the customers' lines are provided. First office 1.64 1.92 0.65 4.18 3.92 3.12 Second office 7.82 3.78 1.12 3.17 0.78 1.37 Assume that the waiting time of the first office and the waiting time of the second office are normally distributed with unequal variances. Let /1 be the mean waiting time of the first office and M2 be the mean waiting time of the second office. Test if there is any evidence of a difference in the mean waiting times between the two offices at a 0.04 level of significance. Compute the standardized test statistic and p-value. Round to 3 decimal places. test statistic= -0.356 p-value= 0.729 O test statistic= -2.544 p-value= 0.011 test statistic= -0.356 p-value= 0.731 test statistic=0.356 p-value= 0.279
