Test the given claim. assume that a simple random sample is selected from a normally distributed population. use the critical value method of testing hypothesis. a. the stewart aviation products company uses a new production method to manufacture aircraft altimeters. a simple random sample of 81 altimeters is tested in a pressure chamber, and the errors in altitude are recorded as positive values (for readings that are too high) or negative values (for readings that are too low). the sample has a standard deviation of s = 52.3 ft. at the 0.05 significance level, test the claim that the new production line has errors with standard deviation different from 43.7 ft, which was the standard deviation for the old production method. if it appears that the standard deviation has changed, does the new production method appear to be better or worse than the old method?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
