An experiment was made to measure the mean number of axe strikes that is necessary to cut a tree trunk. A total of 16 identical tree trunks were cut by a randomly chosen person, and the following data (number of axe strikes) was collected: 52, 54, 56, 55, 57, 47, 53, 45, 46, 48, 55, 57, 51, 54, 56, 52. Is there sufficient evidence to conclude that the median number of strikes is 50?

A costume jewelry pendant made of cubic zirconia is submerged in
oil. A light ray strikes one face of the zirconia crystal at an
angle of incidence of 29?
Once inside, what is the ray's angle with respect to the face of
the crystal? Note that the angle we need to find is complementary
to the refraction angle.

In an experiment designed to measure the speed of light, a laser
is aimed at a mirror that is 47.5 km due north. A detector is
placed 116 m due east of the laser. The mirror is to be aligned so
that light from the laser reflects into the detector.
(a) When properly aligned, what angle should the normal to the
surface of the mirror make with due south?
(b) Suppose the mirror is misaligned, so that the actual angle...

In an experiment to measure the wavelength of light using two
slits, it is found that the interference fringes are too close
together to easily count them. To spread out the fringe pattern,
one could…
A. Increase the slit separation
B. Decrease the slit separation
C. Increase the distance from the slits to the viewing
screen
D. Decrease the distance from the slits to the viewing
screen
E. Both increasing the distance from the slits to the viewing
screen and...

In an experiment, a student was asked to measure the desity of
an unknown liquid. He was given a small flask, which he found to
have a mass of 32.6195 grams when empty. He filled the flask with
water at 21.6 (0.997860 g/mL) degrees C and found the full flask to
have a mass of 156.8995 grams. The student then emptied and dried
the flask and then filled the flask with an unknown liquid. The
mass of the flask filled...
