A psychologist is studying the effect of belly stars on Sneetches. A random sample of four Sneetches is drawn, and a test of self-image is given to each Sneetch before and after having the belly star status changed. (If the Sneetch initially had a star, it was removed; if it did not have a star, one was created on the Sneetch using the patented “Star-off/Star-on” procedure.) From the following sample data, construct a 98% confidence interval on the population mean change in self-image associated with a star status change.
