In an experiment to investigate the performance of four different brands of spark plugs intended for use on a 125-cc two-stroke motorcycle, five plugs of each brand were tested and the number of miles (at a constant speed) until failure was observed. The partial ANOVA table for the data appears below. degrees of freedom Sum of Mean Source squares square Evalue Brand Error 14,713.69 Total 310,500.76
Question 2: Consider again that the company making tires for bikes is concerned about the exact width of its cyclocross tires. The company has a lower specification limit of 22.8 mm and an upper specification limit of 23.2 mm. The standard deviation is 0.15 mm and the mean is 23 mm. What is the probability that a tire will either be too wide or too narrow?

Question content area Part 1 Refer to Table S6.1 - Factors for Computing Control Chart Limits (3 sigma) LOADING... for this problem. Twelve samples, each containing five parts, were taken from a process that produces steel rods at Emmanual Kodzi's factory. The length of each rod in the samples was determined. The results were tabulated and sample means and ranges were computed. The results were: Sample Sample Mean (in.) Range (in.) Sample Sample Mean (in.)

QUESTION 19 It was found that the mean annual tumover rate of the Aspirin medicine bottle is 22. The management think that the mean is changed. Therefore, a random sample of 92 is chosen that shows the average is 19 and the standard deviation is 12. Use 0.07 significance level to test this claim. Based on the above, the test statistic is equal to? (Round answer to two decimal places ex. 2.09)
