T-Test of difference = 0 (vs ≠): T-Value = 0.40 P-Value = 0.691 . DF = 44. Both use Pooled StDev = 9.5745. p-value > thus we fail to reject Ho at =.05. We do not have sufficient evidence to conclude that there exists a difference in the mean temperatures for the thermostats from the two suppliers.

T-Test of mean difference = 0 (vs not = 0): T-Value = 1.90 P-Value = 0.099. Test for true means in single samples. Test of mu = 3800 vs mu not = 3800. Variable 95.0% CI T P. B1 ( 33803, 43156) 17.55 0.000. B2 ( 33224, 41998) 18.24 0.000. Test for equal variances: B1 versus B2. F-Test (normal distribution) ...

The formula to compute that t is . Now, use SPSS to conduct an independent samples t test comparing boys and girls on GPA. Compare the absolute value of the “equal variances assumed” t with that computed from the formula above. Phi Coefficient. The correlation between two dichotomous variables is know as the phi coefficient.

T-Test of difference = 3 (vs >): T-Value = -0.39 P-Value = 0.648 DF = 22. Both use Pooled StDev = 10.1. 2-21. In semiconductor manufacturing, wet chemical etching is often used to remove silicon from the backs of wafers prior to metalization. The etch rate is an important characteristic of this process. Two different etching solutionsare being ...

Pooled-t test. Definitions Two samples are . independent. if the sample values selected from one population are not related to or somehow paired or matched with the sample values selected from the other population. If there is some relationship so that each value in one sample is paired with a corresponding value in the other sample, the ...

Dollar value of the contract. The greater the cost risk to the contractor, the greater the benefits that can be derived from an FPEPA contract. In the DoD, adjustments based on actual labor or material cost are generally not used for contracts of $50,000 or less (DFARS 216. 203-4(c)).

(Eqn 8) D = C + 2 – P = 1 + 2 – 1 = 2. There are two degrees of freedom in a single-phase region of a single-component system- thus 2 parameters of the system can vary and that single phase will remain in equilibrium. This is shown in the diagram by the range of T and P …
