- The percentage of hardwood concentration in raw pulp, the vat pressure, and the cooking time of the pulp are being investigated for their effects on the strength of paper. Three levels of hardwood concentration, three levels of pressure, and two cooking times are selected. A factorial experiment with two replicates is conducted, and the following data are obtained: (Use a=0.05 unless otherwise specified)

Montgomery gathered data on an experiment in paper production to determine the effects of
pulp cooking time (having two levels: 3 hours and 4 hours),
vat pressure (having three levels: 400, 500, and 650), and
percent of hardwood concentration (having three levels: 2, 4, and 8)
on the response variable: paper strength.

Brownstock pulp and associated black liquor is stored in the
blowtank after batch kraft cooking. From the blow tank it is pumpe
at 12% consistncy to a diffuser washer(Modified norden equal to 5)
followed by a vaccum drum washer(modified norden equal to 3). The
dilution factor for the washing operation is 2kg fresh water per kg
of dry pulp. The pulp and wash liquor move countercurrently in
three washers. after the drum washer the pulp becomes part of the

A manufacturer of paper used for making grocery bags is
interested in improving the tensile strength of the product.
Product engineering thinks that tensile strength is a function of
the hardwood concentration in the pulp and that the range of
hardwood concentrations of practical interest is between...

A recent study on the effect of raw garlic on plasma lipid
concentration in adults with moderate hypercholesterolemia was
conducted using 49 randomly selected subjects treated with raw
garlic and 48 randomly selected subjects with a placebo.
The 49 subjects treated with raw
garlic had LDL cholesterol measurements with a mean of 151 and a
standard deviation of 15, while 48 subjects given placebos had LDL
cholesterol measurements with a mean of 149 and a standard
deviation of 14.
