After they practiced the song 5 times, the number of mistakes each student made was recorded. The data are shown. At a=0.05, can it be concluded that there was a decrease in the mean number of mistakes? Assume that all variables are normally or approximately normally distributed. Let u₁ be the mean before and HD H1 H2. Use the P-value method and a TI-83 Plus/TI-84 Plus calculator.
