pvalues and tdistributions 
20071113 

From Don: I have a ttest statistic of 1.28 and a degree of freedom of 6.
I know the pvalue is .248 I cannot figure out how to calculate that value.
I have used software to get it but I want to know how to calculate it using
the tdistribution table. Answered by Harley Weston. 





The pvalue 
20040725 

From Kathy: Ms. Lisa Monnin is the budget director for the New Process Company. She would like to compare the daily travel expenses for the sales staff and the audit staff. She collected the following sample information.
At the .10 significance level, can she conclude that the mean daily expenses are greater for the sales staff than the audit staff? What is the pvalue?
Having problems finding the pvalue & unsure of the formula.
