Problem 12E

(In some of the exercises that follow, we must make assumptions, such as normal distributions with equal variances.)

A particular process puts a coating on a piece of glass so that it is sensitive to touch. Randomly throughout the day, pieces of glass are selected from the production line and the resistance is measured at 12 different locations on the glass. On each of three different days, December 6, December 7, and December 22, the following data give the means of the 12 measurements on each of 11 pieces of glass:

CHEM 001W Prep for General Chem 9/28/2016 ­ CH 1 PT II Measurement & Calculations Why do we care about measurements In order to collect data in the course of scientific inquiry, we often need to make measurements. We also need to manipulate measurements in order to interpret them. Measurements & Fundamental Units ● Distance (meters) ● Mass (grams) ● Time (seconds) ● Temperature (Celsius or K) Measurements & Derived Units ● Volume (centimeters^3 or liters) ● Density (grams/liters) ● Energy (Joule) Making a measurement & significant digits Using a graduated cylinder to make a volume measurement ­ Read from bottom of meniscus (ex: 9.51mL → 3 significant
