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.

Watching TV: The general Social Survey asked a large number of
people how much time they spent watching TV each day. The mean
number of hours was 3.09 with a standard deviation of 2.93 . Assume
that in a sample of 34 teenagers, the sample standard deviation of
daily TV time is 4.1 hours, and that the population of TV watching
times is normally distributed. Can you conclude that the population
standard deviation of TV watching times for teenagers differs...
