Task IV - Essay Example normal time (refueling break time) and number of wins for top 30 Sprint Cup Drivers (the Nextel Cup Series) for year 2008 (entire season) is taken for bivariate connection and relapse investigation. For this paper, the normal time (refueling break time)1 and number of wins for top 30 Sprint Cup Drivers (the Nextel Cup Series) for year 2008 (entire season) is gathered (Race results, 2008; Sprint Cup Drivers, 2008). Table 1: Driver’s Number of Win(s) and the Pit Stop Time in Appendix, shows the information for top 30 drivers for the Nextel Cup Series, 2008. In bivariate relationship and relapse examination , it will be resolved whether normal time of refueling breaks is identified with the quantity of wins. Along these lines, the normal time will be taken as autonomous variable (x) and the quantity of wins will be taken as needy variable (y). Figure 1 shows the disperse plot of Average Pit Stop Time and Number of Wins. From figure 1 , it tends to be considered that to be the normal refueling break time builds the quantity of wins diminishes. Along these lines, there is a negative relationship exists between the factors normal time and number of wins. The estimation of test connection coefficient , r = - 0.55 demonstrate that there is a negative relationship present between the factors normal refueling break time and number of wins for top 30 Sprint Cup Drivers. The relationship is critical at level of hugeness, ÃŽ ± = 0.01. For a two-followed test at level of hugeness, ÃŽ ± = 0.01 and level of opportunity 28, the basic estimation of r is  ± 0.463. The estimation of relationship coefficient r = - 0.550 is not exactly the left tail basic estimation of - 0.463, accordingly the invalid speculation of no connection is dismissed and the information give adequate proof of connection between's factors normal refueling break time and number of wins (Table 3: Correlation Matrix). The slant equivalent to - 1.803 recommends that an extra second in normal refueling break time diminishes the quantity of wins of run cup drivers by around 1.8. The quantity of wins for
