    T-testing of two samples(question about t-statistic)

    Hi have two questions regarding an t-test assignment i did. Basically the null hypothesis was that if sample x2 differed 35 off the mean from sample x1 was it reject-able? The mean of sample x is 395 The mean of sample ý is 435. So the issue is that i think the nominator for the t-statistic...

    So i did a minitab ANOVA test, it spat out a F-Value. A question in an assignment needs me to give them a t-statistic. Can i use this F-value as the t-statistic? Or do i need to do some sort of calculation to get the T-statistic. Sorry if this is a dumb question, ive looked online for...

    Can I trust a regression if variables are autocorrelated?

    Hello everyone! Both variables (dependent and independent) show autocorrelation effects. When I run regression and estimate the residuals, they are not autocorrelated and durbin-watson statistic is small. Can I trust my regression output, are the t-statistics reliable? thank you :)
