can you plz solve these questions for me

1. A study in transportation safety collected data on 42 North American cities. From each city, two of the variables recorded were explanatory variable x=percentage of licensed drivers who are under 21 years of age, and the response variable y=the number of fatal accidents per year per 1000 licenses. Of interest is the relationship between these two variables. The data were analyzed. Examine carefully the output below: Regression Analysis - Linear model: Y = a + b*X Parameter Std. Estimate Error T Statistic p-value Intercept -1.59741 0.371671 -4.29792 0.0001 Slope 0.287053 0.0293898 9.76711 0.0000 Correlation Coefficient = 0.839387 R-squared = 70.4571 percent Standard error of estimate = 0.58935 a) What is the correlation coefficient in this question, and what does it indicate about the relationship between the number of fatal accidents and the percentage of licensed drivers? [3 marks]b) Is there a significant linear relationship between the number of fatal accidents and the percentage of licensed drivers? Support your answer using a decision point and show all necessary steps. [3 marks]c) Write down the equation of the estimated regression line in the context of this question. [1 mark] d) Provide an interpretation of the slope of the estimated regression line in (c), paying special attention to the units of measurement for the data. [2 marks] e) Provide an estimate of the number of fatal accidents when the percentage of licensed drivers who are under 21 years of age is 35. [1 mark] 2.
