A)Adult men have heights with a mean of 69.0
inches and a standard deviation of 2.8 inches. Find the height of a
man with a z-score of 0.8214 (to 4 decimal
places)
B)For a 4-unit class like Statistics, students
should spend average of 12 hours studying for the class. A survey
was done on 29 students, and the distribution of total study hours

A group of students estimated the length of one minute without
reference to a watch or clock, and the times (seconds) are listed
below. Use a 0.01 significance level to test the claim that these
times are from a population with a mean equal to 60 seconds. Does
it appear that students are reasonably good at estimating one
minute?
