STAT210prob3.14: Tensile Strength of Different Fibre Blends

Description

A product developer is investigating the tensile strength of a new synthetic fibre that will be used to make cloth for men's shirts. The strength is usually affected by the percentage of cotton used in the blend of materials for the fibre. The engineer conducts a completely randomized experiment with five levels of cotton content and replicates the experiment 5 times.

Usage

STAT210prob3.14

Format

A data frame with 25 observations (rows) and 2 variables (columns).

	Column name	Data type	Description	Values
[,1]	Cotton_Weight	integer	Percentage weight of cotton in the blend	(15 - 35)
[,2]	Observations	integer	The tensile strength of the fibre	(7 - 25)

Details

This is data from Exercise3.14 in Design and Analysis of Experiments, 9th Edition, EMEA Edition.
