\text { week 4 } & 8 & 6 & 7 & 9 \
\text { week 5 } & 4 & 2 & 5 & 10
\end{array}$$
A)The physicians differ in the no-show rates.
B)The no show rates differ by day of week

The null hypothesis in this context typically assumes no difference or effect, so stating that the no-show rate between physicians is equal aligns with this principle. It posits that any observed differences in no-show rates across the physicians are due to random chance rather than a real difference in their rates.
