Reference no: EM131015105

1. Consider the following data on the diameter of ball bearings from a particular production line.

1.18 1.42 0.69 0.88 1.62 1.09 1.53 1.02 1.19 1.32

(a) Find the sample mean and the sample variance.

(b) Find the IQR.

2. A chemical process was run using two different alcohols (Factor A) and three different bases (Factor B). The process was run twice with each alcohol/base combination, and the resulting yields are given below.

	Base
Alcohol	93	76	65
	95	78	61
	60	75	95
	64	79	93

Draw an interaction plot for these data. What would you conclude?
