Questions 11-13 refer to the following: Part variability is critical in the manufacturing of ball bearings. Large variances in the size of the ball bearings cause bearing failure and rapid wearout. Production standards call for a maximum variance of 0.0001 when the bearing diameters are measured in inches. A sample of 15 bearings shows s"-0.000196. Use or=0.05 to determine whether the sample indicates that the maximum acceptable variance is being exceeded. The test statistic is O 2744 1960 274400 O 29.4 Questions 11-13 refer to the following Part variability is critical in the manufacturing of ball bearings. Large variances in the size of the ball bearings cause bearing failure and rapid wearout. Production standards call for a maximum variance of 0.0001 when the bearing diameters are measured in inches. A sample of 15 bearings shows s-0.000196. Use a-0,05 to determine whether the sample Indicates that the maximum acceptable variance is being exceeded. What is the critical value? 23.685 O 21.064 24.996 22 307 Questions 11-13 refer to the following: Part variability is critical in the manufacturing of ball bearings.

Use a=0.05 to determine whether the sample indicates that the maximum acceptable variance is being exceeded. ) Reject the nul There is sufficient evidence that the maximum acceptable variance is being exceeded Do not reject the nul. There is sufficient evidence that the maximum acceptable variance is being exceeded. ) Reject the null. There is sufficient evidence that the maximum acceptable variance is not being exceeded. O Do not reject the null. There is sufficient evi ceptable variance is not being exceeded
