The two-sample t statistic is We find the P-value by comparing 0.654 to critical values for the t(132) distribution and then doubling p because the alternative is two-sided. Table D (for 100 degrees of freedom) shows that 0.654 does not reach the 0.25 critical …

3. Use density tool. Choose mean. Enter Mean=931, s=333, n=30 if you move your flag it leaves the screen at 1113 anything above that value has a p-value less then .0001in particular our sample mean 1131 has p-value less than.0001 consequently. We will reject H0 at 5% level. *Finish Interpretation…. WEN-8. The Focus Database
