Matched-pairs test, directional, classical hypothesis testing method
The impact assessment committee of the Intermountain National Park Service Region is concerned about increased vehicle traffic in Utah’s 5 national parks. Data collected from 1996 and 2016 show the total traffic counts for each park. Use classical hypothesis testing and the data below to determine if there has been a statistically significant increase in the number of vehicles entering Utah national parks over this 20 year period at the 99% confidence level. (Hints: 1) one tailed test, 2) matched-pairs t-test.)
