The content of a sample of 22 cans of apple juice showed a
standard deviation of 0.04 ounces. At a 0.10 level of significance,
we are interested in testing to determine whether the variance of
the population is significantly less than 0.002.
I. The correct null hypothesis is:
II. The critical value is: The letter associated with
the correct answer is
a) 13.24
b) 16.8
c) 29.615
d) 37.652
e) None of the above
III. The estimated value is: The letter associated
with the correct answer is
a) 13.24
b) 16.8
c) 29.615
d) 33.6
e) None of the above
IV. At 90% confidence, it can be concluded that the
variance of the population is: The letter associated with the
correct answer is
a) significantly greater than 0.002
b) not significantly greater than 0.0016
c) significantly less than 0.002
d) not significantly less than 0.002
e) None of the above
