To test this claim, a random sample of 1000 automobile owners are asked to keep a record of the miles they travel. Would you agree with this claim if the random sample showed an average of 11850 miles and a sta ...

... with the aid of the t-test and tables or an appropriate computer program. If we plug our numbers in from the data table, we find that the "Standard Error of the Difference" for our 4 mm length difference is 2.29 mm. The next step in the process is to use our value for sdiff to calculate a t-score. T ...
