A battery manufacturer advertises that the average life of their batteries is 900 hours. A random sample of 15 of its batteries resulted in the following lives in hours: 995 916 590 728 510 664 539 693 739 708 917 887 849 571 555 At 10% significance level, do the data provide evidence that the mean life for the company's batteries differentiations from the advertised mean? Compute for the statistical test. Use 3 decimal places and indicate if the computed value is + or -.
