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, does it appear that changing belly star status increases the average self-image of Sneetches? Select the appropriate critical value (CV), test statistic (TS), and decision.(Use α = 0.10).
