Determine the margin of error that would be used to estimate the slope for a least squares simple linear regression model if the (standard error) simple regression estimator for the standard deviation of the slope was 3.55, there were 24 observations in the data set for the sample, and the desired level of significance (alpha) is 0.20. Use the appropriate critical value of t, as shown to four decimals in the book. The correct answer is 4.69. I just need to know how to get to the correct answer.
