Question
Stereograms Stereograms appear to be composed
entirely of random dots. However, they contain separate
images that a viewer can “fuse” into a three-dimensional
(3D) image by staring at the dots while defocusing the
eyes. An experiment was performed to determine whether
knowledge of the form of the embedded image affected
the time required for subjects to fuse the images. One
group of subjects (group NV) received no information
or just verbal information about the shape of the embed-
ded object. A second group (group VV) received both
verbal information and visual information (specifically, a
drawing of the object). The experimenters measured how
many seconds it took for the subject to report that he or
she saw the 3D image.
2-Sample t-Interval for m1 - m2
Conf level = 90, df = 70
m(NV) - m(VV) interval: (0.55, 5.47)
a) Interpret your interval in context.
b) Does it appear that viewing a picture of the image
helps people “see” the 3D image in a stereogram?
c) What’s the margin of error for this interval?
d) Explain what the 90% confidence level means.
e) Would you expect a 99% confidence level to be wider
or narrower? Explain.
f) Might that change your conclusion in part b? Explain.
