Fractional Factorial Project 1 Assignment Investigate the performance of an injection-molding machine used in the manufacturing operations of the Mouse Factory. The response (output) variable is density (of a molded part). The range of settings for each factor is shown below.

	Settings
Variable	Minimum	Maximum	Units
Mold Temperature	100	200	degrees C
Injection Velocity	1	4	ft/sec
Mold Pressure	500	950	psi
Back Pressure	50	150	psi
Cooling Time	1	120	seconds

Assignment Provide information regarding the condition of the process and make both point and interval estimates for future values of density at the initial setting.

Initial Setting Analysis Your analysis should contain three major components: a graphical analysis of density, a numerical summary of density and predictions of future performance of density in both a point estimate and interval estimate (with appropriate significance level).
