It's common for a movie's ticket sales to open high for the first couple of weeks, then gradually taper off as time passes. Hoping to be able to better understand how quickly sales decline, an industry analyst keeps track of box office revenues for a new film over its first 20 weeks.

◦ t-Interval for slope
◦ χ2 goodness-of-fit test
◦ 1-proportion z-test
◦ t-test for linear regression
◦ t-Interval for a mean
