The operations manager of a plant that manufactures tres wants to compare the actual her dames of heo grades of Sies, each of which is expected to be 575 milimeters Samples of the tres from each grade were saat and the presenting the inner diameters of the tres, rarked from smafest to targest, are shown below Complate parte (a) through (below Grade X Grade Y 667 670 576 582 684 674 575 576 580 581 For each of the two grades of tires, compute the meat, medan, and standard deviation The mean for Grade Xis (Type an integer or a decimal) The mean for Grade Yis (Type an inager or a decimal The median for Grade Xis (Type an integer or a decimal m The median for Grade Y is (Type an integer or a decimal) The standard deviation for Grade Xim (Type an integer or decimal rounded to two decimal places a reeded) The standard deviation for Orade Vism (Type an integer ori timal rounded to two decimal places as needed) b. Which grade of tire is providing better quality? Explain Choose the comect answer below OA Grade X provides the better quality While the mean of Grade Y is closer to the expected mean, the standard deviation of Grade X much smaler OB Grade X provides better quality because its mean is much smaller word b. Which grade of sire is providing better quality? Explain. Choose the corect answer b OA Grade X provides the better quality. While the mean of Grade Y is closer to the expected mean, the standard deviation of Grade X is much smal OB Grade X provides better quality because its mean is much smal OC. Grade Y provides the better quality. While the mean of Grade X is closer to the expected mean, the standard deviation of Grade Y is much smaler OD Grade provides better quality because its mean is much smaller c. What would be the effect on your answers in (a) and (b) the last value for Grade Y were 580 instead of 5817 Explain Choose the correct anewer below When the fifth Grade Y tine measures 569 mm rather than 581 mm, Grade Y's mean inner diameter becomes mm, which is this case, Grade X's tires are providing quality in terms of the mean inner diameter (Round to two decimal places as needed.) Than Grade X's men inner diameter and Grade Y's standard deviation changes from mini tom Clear all Check arise The operation manager of a plant that manufactures tres wants to compare the actual inner diameters of two grades of tres, each of which is expected to be 575 millimetas. Samples of five tires from each grade were selected, and the resu representing the inner diameters of the tires, ranked from smallest to largest, are shown below. Complete parts (a) through (c) below Grade X Grade Y 9 567 570 570 582 584 574 575 576 580 581 a. For each of the two grades of tires, compute the mean, medien, and standard deviation The mean for Grade X is mm (Type an integer or a decimal) The mean for Grade Y is mam (Type an integer or a decimal) The median for Grade X is mm (Type an integer or a decimal) The median for Grade Y is m (Type an integer or a decimal) The standard deviation for Grade X is mm. (Type an integer or decimal rounded to two decimal places as needed) The standard deviation for Grade Y is (Type an integer or decimal rounded to two decimal places as needed.) b. Which grade of the is providing beter quality? Explain Choose the correct answer below OA. Grade X provides the better quality. While the mean of Grade Y is closer to the expected mean, the standard deviation of Grade X is much smaler OB. Orade X provides beter quality because its meat is much smaller b. Which grade of fire is providing better quality? Explain Choose the comect answer below OA Grade X provides the better quality. While the mean of Grade Y is closer to the expected mean, the standard deviation of Grade X is much mater OB Grade X provides better quality because its mean is much smalle OC. Grade provides the better quality. While the mean of Grade X is closer to the expected mean, the standard deviation of Grade Y is much smaller OD. Grade Y provides better quality because its mean is much smater e. What would be the effect on your answers in (a) and (b) if the last value for Grade Y were 589 instead of 581? Explais. Choose the comect answer below When the fifth Grade Ytre measures 569 mm rather than 581 mm, Grade Y's mean ever diameter becomes which is than Grade X's mean inner diameter, and Grade Y's standard deviation changes from mm quality in terms of the mean inner dame this case, Grade X's tres are providing (Round to two decimal places as needed.)
