Problem $33(1$ point$)$

A major airline is attempting to evaluate the effect of recent changes it has made in scheduling flights between New York City and Los Angeles. Data available are shown below:

Number of flights Number of Passengers

Month prior to schedule change $($January$)168,795$

Month after schedule change $($June$)2715,653$

Using January as the base period, compute a productivity index for January and June, and comment on what those productivity indexes tell about the productivity trend.
