ASHFORD BUS 308 Week 2 DQ 1 Relative Frequency
(Old)
Relative Frequency. Conceptually we would expect
the probability of newborn males and females to
be the same. However, census reports indicate
that the ratios of males and females in various
countries do not conform to the theoretical
prediction. What do you think accounts for this
variation? Can you think of other cases where the
expected probabilities do not quite agree with
the empirical values?

(Old)
Unscientific Sampling. Consider question 7.45
from the text A Milwaukee television station,
WITI-TV, conducted a telephone call-in survey
asking whether viewers liked the new newspaper,
the Journal Sentinel. On April 26, 1995, Tim
Cuprisin, a columnist for the Journal Sentinel,
wrote the following comment WITI-TV (Channel 6)
did one of those pollswhich they admit are
unscientificlast week and found that 388 viewers
like the new Journal Sentinel and 2,629 didnt
like it. We did our own unscientific poll on

percent of the respondents say absolutely,
positively not.Is Cuprisins comment justified?

ASHFORD BUS 308 Week 4 DQ 2 Creating Hypotheses
(Old)
Creating Hypotheses. Assume you are the manager
of a paint manufacturing factory. Your company
has received complaints from customers that the
containers hold less than the amount printed on
them. On the other hand, corporate management is
concerned that the containers hold more than the
standard amount. You assign a statistician to
verify these claims. A sample of containers was
selected and the volume of paint in each
container was measured. Assuming that the volume
printed on each container is 1 gallon, how would
you formulate the null and alternative hypotheses
to test the customers claim? As a manager, what
reasonable criteria will you use to set a value
for the level of significance to be used in the
test? After answering this question, what type of
error would you suppose may result in that case?

p-value to test H0 versus Ha by setting a equal
to .10. We reject H0 at level a of significance
if and only if the p-value is 2.
Question When carrying out a sample test
(with ó known) of H0 µ 10 vs. Ha µ gt 10 by
using a rejection point, we reject Ho at level of
significance a if and only if the calculated test
statistic is 3. Question When
using the chi-square goodness of fit test, if the
value of the chi-square statistic is large
enough, we reject the null hypothesis. 4.
Question The actual counts in the cells
of a contingency table are referred to as the
expected cell frequencies. 5. Question
For a hypothesis test about a population
mean or proportion, if the level of significance
is less than the p-value, the null hypothesis is
rejected.
