MTH 233/Elementary Statistics
In this paper, Team A will be determining and discussing how there will be an overall shortage of truck drivers in the years of 2012 and 2014. We will be using a null hypothesis and alternative hypothesis to determine which hypothesis is correct. The subject that is being testing is the issue of a possible decrease in the number of truck drivers that are present on our roads today.
A hypothesis test is being conducted to test the shortage of truck drivers in the coming years. Within the past years, the trucking industry has seen a decrease in the number of drivers on the road. This is due in part to the economy as well as the many regulations that are placed upon the industry (Beard, 2011). These regulations include the number of hours that truck driver is able to drive as well as the number of potential drivers who are unable to pass the mandated drug testing and if these potential drivers have a DUI (driving under the influence) within the past five to 10 years. Another reason for the shortage is that many of the younger population in the job force are seeking employment in the technology business; leaving an older population who is in this field who will retire in the approaching years. With these issues at hand, we can now look at the changes and how this will affect the hypothesis that is stated below. Five Step Hypothesis Testing Process
Year| CPS Estimate of # of Truck Drivers|
Hypothesis 1: Stating the research question:
There is an overall shortage of truck drivers as the years 2012 and 2014 approach. It is said that the average shortage is from 1.4% to 0.5% per year. Using a significance level of 0.05 we are testing the claim whether the shortage of truck drivers in the year 2012...
