For a data set of 10 values of x and y, the value of SSw = 83, the standard deviation of errors for the regression of y on x is 2.867, and the value of b is 1.63. For the purpose of conducting a hypothesis test, the null hypothesis is that the slope of the population regression line of y on x is zero and the alternative hypothesis is that the slope of this population regression line is different from zero. The significance level is 5%. What is the value of the test statistic, t, rounded to three decimal places?
