Please help, if possible could you explain the conclusion thourugly

2. The National Highway Traffic Safety Administration (NHTSA) performed a series of brake tests to evaluate variability in the results obtained at the different facilities and among different drivers. This table displays the braking distance, in feet, from two different test sites for the Chevrolet Blazer on dry surface. Stopping Distance Statistics, Chevrolet Blazer Stop Number 6 8 10 11 12 13 14 Site 1 162.9 160.47 161.36 155.73 156.43 155.07 159.9 161.45 163.04 158.44 Site 2 169.47 162 91 160.34 159.95 164.06 157.92 1648 159.96 163.61 155.11 167 74 164.74 163.68 166.75 Summary Statistics Site 1 Site 2 Average Stopping Distance (ft) 159.48 162.93 Standard Deviation of Stopping 2.92 3.92 Distances (ft) Number of Stops Analyzed 10 14 Is there statistically significant evidence that the average braking distance at the two test sites is different? Explain using the four-step process and test at the 5% level of significance. As there is no information about the design of this study, treat it as an observational study when you write the conclusion. Si
