An experiment was conducted to study the extrusion process of biodegradable packaging foam. Two of the factors considered for their effect on the foam diameter (mm) were the die temperature(145°C vs.155°C) and the die diameter (3 mm vs. 4 mm). The results are in the accompanying data table.The question are attached in a photo Foam Diameter vs. Die Diameter and Die TemperaturDie Temperature Die Diameter (mm)3145145145145145145145145145145145145155155155155155155155155155155155155w w w w w w333334444443333334+++++44444Foam Diameter8.389.5410.579.2710.449.2710.747.4910.728.099.619.968.8610.7312.9912.468.7410.549.3511.1510.596.7110.3911.23 a. is there an interaction between die temperature and die diameter?b. is there an effect due to die temperature?c. is there an effect due to die diameter?d.

In the experiment, a group of college students was told that they were participating in a manual dexterity study. Half of the students were given a stack of money to count and the other half got a stack of blank pieces of paper. After the counting task, the participants were asked to dip their hands into bowls of very hot water (122°F) and rate how uncomfortable it was. The following data show ratings of pain similar to the results obtained in the study. A. State null and alternative hypotheses b. Report results of statistical test, i.e., significant or not?
