The City of Long Beach experienced many crashes involving bicyclists in one location. Bike lanes were implemented in order to reduce the number of crashes. Using t-test, perform hypothesis testing to determine the effectiveness of bike lanes in this location at 5% level of significance (ta/2= 2.447). Use the following data. Year 1 Year 2 Year 3 Year 4 Average Standard deviation Before implementation 23 19 25 21 22.00 2.236 After implementation 20 18 24 22 20.33 2.256 Null Hypothesis: There is no difference in the number of accidents before and after implementation of bike lanes. Alternative Hypothesis: There is a difference in the number of accidents before and after implementation of bike lanes. Based on your analysis, the t-value is (use three decimal places): Is there a significant difference in the number of accidents before and after implementation of the bike lane (yes or no)? Explain what it means. A
