Question
The New York state auditor examined the total dollar amount of computation errors in a random sample of 11 NYS "small" tax returns. The sample gave the following computation errors: 474, 454, 382, 501, 408, 564, 603, 345, 400, 571, 419 Computation errors in NYS "small" tax returns are known to be normally distributed. with an unknowwn mean of u and an unknown standard deviation o. Calculate the sample range for this data. (One number) Calculate the sample variance for this data. Suppose W has at distribution with 10 degrees of freedom. If P(W > t) = .05 then what is t?
