The altitude of a spot is mentioned on map as 295 m. The success
rate of a missile launched from this point in hitting its target
will depend upon the accuracy of the altitude, and therefore the
commander ordered to collect 50 measurements with precision GPS
instrument. The sample mean was 297.6 m, with a standard deviation
of 12 m. Does this measured altitude provide enough evidence to
reject the mentioned altitude on map at 5% level of
significance?
[Answer: No, zcomp = 1.53, zcrit = 1.96]
