First, correlation predicts where X (the measured value of interest) falls on a line given a known value of Y. Second, it expresses a reduction in variability associated with knowing Y, telling us something about the expected range of the X value.15 Correlation takes into account the full range of scores, but as a statistical tool it is not very sensitive to scores on the very high or very low ends of our X value. The common Pearson correlation is best used to describe linear relationships. If the pattern of association between the two variables is, for example, a "U" shaped curve, the correlation results might be low, even though a defined relationship exists.

1. How does the shortness of the CO2 molding achieve effectiveness when the Short gassing time is highly applied?

2. Why is it such that the withdraw from CO2 molding Rough patterns is always a difficult task?

3. Critique accordingly; Overgasing increases the core strength.

4. Elaborate on the additive feature of the dextrin while dealing with sodium

5._____________ increases SiO2-Na2O ratio that increases the bond. Explain

6. Elaborate on the molding process while dealing with the Clay is used in the CO2

7. How is impairment led into as gas is passed longer than required

8. justify/falsify; CO2 used in CO2 molding is at high pressure.

9. What is the effective use of the Sodium Silicate while biding onto the CO2 moulding?

10. The use of CO2 was to __________ the sand mould.elaborate
