Use information from the table to answer the following questions. The standard deviation of the residual for the sixth observation y6-12.3110 is residual for the sixth observation is . The standardized 0.5604 0.2514 0.5614 0.0500 You can obtain a studentized deleted residual using so, the standard error of thmputed for the regression model with the ith observation deleted. Suppose you have computed a revised standard error of estimate with observation 6 deleted and obtained a value of s(6)0.2300. The revised standard deviation of the residual of the sixth observation (calculated with the sixth observation deleted) is revised standard error of the estimate s(6) to calculate the revised standard deviation of the sixth residual.) The studentized deleted residual for the sixth observation is . (Hint: Use the Use the Distributions tool below to help you answer the following question
