Question
The same projectile experiment was conducted as you did in class. A racquet ball rolls down a
track, leaves the track at an initial height of 0.961m above floor, with an exit speed Vexit 1.40m/s at
an angle exit
7.46°. The landing spot was repeatedly measured for ten times, and the racquet ball's
horizontal range data is provided below.

Please calculate the 95% confidence range of the horizontal range, and report your result in the
format of mean ± 95% range (refer to the Uncertainty.docx document for the correct format.)
