Does the most recent class of 200 MBA students fit that same pattern or has there been a shift in the choice of majors.

shown here into SPSS to assess whether there is a positive
relationship between grit and...

The data show the time intervals after an eruption (to the
next eruption) of a certain geyser. Find the regression equation,
letting the first variable be the independent (x) variable. Find
the best predicted time of the interval after an eruption given
that the current eruption has a height of 149 feet.
