A professor was interested in determining whether the prices of new textbooks in
The bookstore were higher than if purchased online. She selected 6 textbooks and priced
Each at the bookstore and online.
Paired T-Test and CI: Bookstore, Online Paired $\mathrm{T}$ for Bookstore - online

$\begin{array}{lrrrr} & \text { N } & \text { Mean } & \text { StDev } & \text { SE Mean } \\ \text { Bookstore } & 6 & 115.00 & 22.36 & 9.13 \\ \text { Online } & 6 & 105.83 & 13.20 & 5.39 \\ \text { Difference } & 6 & 9.17 & 13.20 & 5.39\end{array}$

95\% lower bound for mean difference: -1.69
T-Test of mean difference $=0(\mathrm{vs}>0) : \mathrm{T}$ -Value $=1.70 \quad$ P-Value $=0.075$
