In the United States, tyre tread depth is measured in 32nds of an inch. Car tyres typically start out with 10/32 to 11/32 of an inch of tread depth. In most states, a tyre is legally worn out when its tread depth reaches 2/32 of an inch. A random sample of four tyres provides the following data on distance driven and tread depth: Distance driven Tread Depth (32nds of an inch) Tyre (10,000 kilometres) 2 3 4 4 4 4...

Problem 4: Variables that may affect Grades The data set contains a random sample of STAT 250 Final Exam Scores out of 80 points. For each individual sampled, the time (in hours per week) that the student spent participating in a GMU club or sport and working for pay outside of GMU was recorded. Values of 0 indicate the students either does not participate in a club or sport or does not work a job for pay. The goal of...

Find some "real world" data. This data needs to have two sets of numbers that correspond to each other in an exponential pattern. Choose data with at least 10 pairs of data values. Caution: Do not select specific problems already in your text! Also, please be careful not to select exponential growth models that do not need data fitting such as doubling models. For example, if you already know a particular model grows by doubling each time period, then you...

Spring Constants & Periods By varying the mass placed on a spring, the period of oscillation can be changed. When multiple data sets are collected and plotted, the spring constant can be determined. Before data was collected, the minimum and maximum masses were determined by visually watching the harmonic motion. For the minimum, a mass was chosen such that the resulting simple harmonic motion had an appreciable amplitude without significant dampening over ten periods. For the maximum, the mass was...
