Homework: Ch 6S Practice Question 9. Problem 68.26 Part 1 of 9 HW Score: 16.98%, 9 of 53 points O Polnts: 0 of 10 Save Refer to Table S6.1 - Factors for Computing Control Chart Limits (3.sigmo) for this problem West Battery Corp. has recently been receiving complaints from retailers that its 9-volt batteries are not lasting as long as other name brands. James West, head of the TOM program at West's Austin plant, believes there is no problem because his batteries have had an average life of 45 hours, about 10% longer than competitors' models . To raise the lifetime above this level would require a new level of technology not available to West. Nevertheless, he is concerned enough to set up hourly assembly line checks. Previously, after ensuring that the process was running properly, West took samples of 5 9-volt batteries for 25 tekt to establish the standards for control chart limits. Those 25 tests are shown in the following table: Sample Data Sample Data nd Hour Sample Taken 3 x 4 x 44.8 1 ne 41 46 42 31 24 22 50 45 40 44 49 44 55 30 R 17 16 30 20 20 28 115 } 26 0 0 4 0 Up 6 hic + *S& nb 45 55 44 47 59 47 45 49 42 45 58 43 54 8&SSSSSSS 44 41 33 45 31 50 42 39 42 41 39 38 40 SSS & 3833 Hour Sample Taken 14 15 16 17 18 19 20 21 22 23 24 25 52 31 53 47 42 50 52 36 39 36 32 56 40 46.4 41.8 41.0 478 41.8 51.6 39.4 46.4 41.6 45.8 46 0 472 466 OSOBND 11mmunsaw 48 51 58 35 58 51 55 48 49 42 44 47 52 38 43 33 46 48 44 41 34 42 44 45 35% %%% , z* m 48 52 28 53 51 43 36 53 45 44 46 46 48 38 43 38 46 35 42 50 45 44 47 28 62 47 41 48 48 65 pwgn 24 26 Pla 43.4 412 47.8 46.6 43.0 43.6 43.6 43.4 44 6 48.4 45 34 40 44 45 57 20 19 16 3 No 8888 tred 38 66 53 51 34 10 11 12 30 26 18 31 12 ser hun This exercise contains only parts a and be a) For the given data, the x = hours (round your response to three decimal places) bloat
