e Swiss Hiking Federation (SHF) is an organization that is responsible for promoting the safe use of the hiking trail system throughout Switzerland. Trails are clearly marked with signposts and the approximate hiking time to assist individuals with their hiking agenda. Suppose the SHF would like to investigate the linear relationship between the amount of time to hike the Wengen-Kleine Scheidegg trail in the Jungfrau region and the age of the hiker. A random sample of seven hikers on this trail was selected and their age and hiking time, in hours, are shown here. Age Time 24 2.7 32 4.2 47 5.0 40 3.8 26 2.2 53 2.9 38 3.0 a) If the sample correlation coefficient is 0.435 what can you say? b) Test to determine if the population correlation coefficient, not equal to zero using a = 0.1. c) Calculate the coefficient of determination for the Swiss hiking data. What can you conclude
