Question
Find the estimated y intercept as well, round to 3 decimal points
480
The table below gives the list price and the number of bids received for five randomly selected items sold through online auctions. Using this data, consider the equation
of the regression line,ŷ = bo+bix, for predicting the number of bids an item will receive based on the list price. Keep in mind, the correlation coefficient may or may
not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation
coefficient is not statistically significant.
Step 1 of 6: Find the estimated slope. Round your answer to three decimal places.
