A TV company is interested in the people watching their period drama show “Downtown Castle” that is set in the early 1900s. They found an overall F-statistic suggesting that together, age and hours of free time significantly predicted the number of episodes of Downtown Castle that people watched in a sample of 30. The slope coefficient for age was 4.5, with a standard error of 2.5
Question1
Based on the Downtown Castle model, calculate the upper boundary of the 95% confidence interval for the age slope coefficient. You can select the critical t-value from the table.
Question2
Based on the Downtown Castle model, calculate the lower boundary of the 95% confidence interval for the age slope coefficient.
