An Internet retailer would like to investigate the relationship between the amount of time in minutes a purchaser spends on its Web site and the amount of money he or she spends on an order. The table to the right shows the data from a random sample of 12 customers. Construct a 90​% confidence interval for the regression slope. Construct a 90​% confidence interval for the slope. LCL equals nothing and UC Lequals nothing ​(Round to three decimal places as​ needed.)
